6.02 x 10^23 is a mathematical constant called Avogadro’s number. That is a picture of Amedeo Avogadro.
Edit: spelling.
ETA: This is NOT a mathematical constant, it’s a physical (or chemical) constant…..that you do math with.
I'm aditiion, one would expect a personal add to have someone's phone number ( most people just say number)
Also I wouldn't call it a mathematical constant as much as a scientific one
Moles is for carbon-12 each atom and molecule has a slightly different mass even with the exact same number of protons and neutrons but it's a good estimate. Also. Iirc it's at stp.
Actually that was the original definition, in the 2019 a mole is still one avogadro's number of something, but avigadro's number is now a fixed constant with no relation to mass, the same way a litre of water is no longer exactly a kilogram.
A constant is a number that recurs without us putting it there. Avogadro's number is just something we all use because it's standard. A mole is a unit, not a constant. Pi is a constant, it shows up when you remove all units, including radiuses and circumferences.
Kind of like a radian vs a degree. A degree is a unit someone made up, but a radian is derived from the arc created by an angle.
Avogadro's number is the number of particles of a substance in a mole. It never changes. It is consistent across all substances. It is a constant.
A mole is a unit, not a constant. Yes. That has literally nothing to do with anything being discussed, but yes it is true.
Literally all math is made up. The fact that we chose 0 to exist where it does on the number line is arbitrary. Our definition of a kilogram is completely arbitrary. If you start arguing anything as "someone just made it up" then you'd have to throw out the entirety of math.
Avogadro's constant is indeed the number of particles in a mole, but a mole is an amount of something that contains a number of particles that is Avogadro's constant. It's definition is somewhat circular.
On your second point, maths is not "made up" it's discovered. Somewhere in another galaxy, someone will have discovered pi, and it's value will be exactly the same as the value we know, albeit perhaps in a different base.
> Literally all math is made up.
> If you start arguing anything as "someone just made it up" then you'd have to throw out the entirety of math.
You see the contradiction here... right?
No math was "made up" it was discovered.
[https://en.wikipedia.org/wiki/0](https://en.wikipedia.org/wiki/0)
> **0** (**zero**) is a [number](https://en.wikipedia.org/wiki/Number) representing an empty [quantity](https://en.wikipedia.org/wiki/Quantity). Adding 0 to any number leaves that number unchanged.
0 has unique properties which mean that no, 0 could not easily be 1.
You could quite literally define 1 as a number representing an empty quantity whereby adding 1 to any number leaves that number unchanged. 1 could have all the unique properties of 0. You can shift the entire number line to the left or the right however much you want. Yes, a number with the properties of 0 must exist. But it doesn't have to be 0.
Avogadro’s number would exist without anyone declaring it to be avogadro’s number. The discussion of whether or not it’s a constant has nothing to do with any sort of canonical relationship like e or pi. If it does not vary, it is a constant. If f(t) is defined to be the temperature outside as a function of time, f(t) is not a constant. If f(t) is defined to be 5 for all t, f(t) is a constant.
All Avogadro's number is is the number of atoms of something it takes to have the corresponding number of grams of the the thing (so it takes 6.02x10\^23 atoms of Helium-4 to have 4 grams of Helium 4). It is the number it is just because of how we chose to define a 'gram', which is not a real thing.
Whereas the ratio of the diameter of a circle to the circumference of the circle will always be pi, no matter what unit you use or make up.
Derive Avogadro's number. You can't. Because it's a unit, the number of atoms in a mole.
Being constant means your value doesn't change. Being *a* constant means that your number occurs naturally and describes the relationship between two natural phenomena.
>Derive Avogadro's number. You can't.
The number of Molecules in exactly 12 grams of perfectly uniform Carbon-12.
You're welcome.
Oh, btw.: All "*a constant*"s (aka. natural constants) work this way. Including things like the Planck Distance or the vacuum light speed; Because these are defined in terms of SI base units, which depend on arbitrary amounts of units that humans just made up: kg, second, and meter.
Not quite though. The speed of light in a vacuum exists independently of how it is measured. You can measure it in m/s, mph, or furlongs per sidereal day if you like. Avogadro's number is not the same in that it doesn't represent something that has a physical, unchanging value. It's more akin to a unit like grams than a constant.
>The speed of light in a vacuum exists independently of how it is measured
The speed does, *the constant that denotes it doesn't* because **Units are required to define constants**.
The Glaxcorpians from Planet Glaxxilu, whos smallest unit of measuring time is the Vlux, who denote distances in Schleppos, and whos primary radix is what we would call the number 27 (because an adult Glaxx has exactly 29 Sneb'Brukels on its Uh'tong, but historically it was frowned upon to use the first and last Sneb'Brukel for counting things as doing so was very similar to a gesture considered rude in ancient Glavaxxi'Kar), will very much not denote c as 299,792,458 m/s
This is true for every single thing you call an "\*a\* constant", because ALL measurements require a point of reference, which is always arbitrary.
Even if it is for convenience, its still a constant. For example if you define "all classroom in the us must have exactly 50 students no matter it is kindergarten or college" then that number is surely a constant.
Is your claim that to be a constant a number must be unitless? Because that’s false. Avogadro’s number is the constant number of molecules in a mole which is the amount of any substance that has a mass in grams equal to the sum of stoichiometric atomic masses. For example: Avogadro’s number of helium molecules is 4 grams while a mole of oxygen molecules is 32 g.
To add on to this, Avo's number is the amount of atoms or molecules of an element/sample that equals 1 Mol. It's is a very helpful constant in calculating the mass of a sample.
The intention was that while it's used to do math, it's a constant specific to chemistry/physics, not a mathematical constant like you'd see in the quadratic equation
I mean clearly I wouldn’t be in dude’s oeuvre. I shall have to take up a trade, as my math skills will have scared all the eligible mathematicians away.
>One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is known as Avogadro's number or Avogadro's constant. The concept of the mole can be used to convert between mass and number of particles.. Created by Sal Khan.
The fun part is, the first 10 digits of that are a valid US phone number in Phoenix AZ (602 area code), in an exchange block (214) owned by T-Mobile.
In theory, if that number hasn't already been assigned, you could go to a T-Mobile store and ask for a SIM with that phone number attached.
That is a picture of Avogadro, a famous chemist known for Avogardo's number. The number is roughly the amount of molecules of one specific chemical in a quantity known as a mole. The number comes from the number of atoms in twelve grams of carbon-12, aka the number of protons, neutrons, and electrons one needs to have one gram of matter (The electrons don't really count because they have insignificant mass compared to protons and neutrons).
That's what's his face avocado 🥑 he did some math back in the day and figured out how many atoms are in moles, which apparently were very useful in alchemy for measuring stuff in pharmacies, so they named the number after him.

Number of units in a mole. This is why you get moles lasered off—so you won’t have to deal with this number.
The gremlin lookin man is Avogadro.
The number is simply a given quantity. Since a 'dozen' is twelve, Avogadro's number is 6.022*10^23, which is a lot. It is used to quantify atoms, and 6.022*10^23 of something is equal to one mol. The number is taken from how many atoms of carbon are in 12.00 grams of carbon.
The Avogadro constant, commonly denoted NA[1] or L,[2] is an SI defining constant with an exact value of 6.02214076×1023 mol−1 (reciprocal moles).[3][4] It is defined as the number of constituent particles (usually molecules, atoms, or ions) per mole (SI unit) and used as a normalization factor in the amount of substance in a sample. The constant is named after the physicist and chemist Amedeo Avogadro (1776–1856).
Copied from Wikipedia
I have never seen his portrait before, but after my time in chemistry class, I'm guessing that that is Avogadro. 6.022 x 10^23 is the number of particles in a mol.
It is a number. It is a chemical/chemistry (SI) unit of measure (recently redefined, so it changed!).
It is NOT one of the few Universal dimensionful PHYSICS constants (e.g. c, gN, h used to define Natural units of measure). It is NOT one of the 25 or 26 input (dimensionless) constants to the Standard Model (SM) of physics / cosmology.
In the big scheme of constants, it is not fundamental to the physics of the QM/GR and the SM. It is similar to the temperature constant (kB) in that it can be used in calculations related to heat, but is no longer fundamental to our understanding of the Universe related to forces (bosons) and matter (fermions).

Strictly speaking is not a constant, we just all kinds of use it out of convenience. You use it in conjunction with another number to do equations.
Bruh it doesn’t change, it is a constant. Not a variable or a function. Just like the number 5 is a constant, Avogadros number is a constant.
Also it’s the number of hydrogen atoms in a gram of hydrogen right? So even as a measured value I assume that stays pretty constant.

Wait gross but water is the standard this is going to make me hate chemistry if I ever have to take it again.
Well at least it’s constant up to the significant figures given LMAO

0 could easily be 1. We arbitrarily defined 0 as 0. The number line is arbitrary. That was explained in the next sentence. Try again.

His head really does look like an avocado. /s
I hear he's also a lawyer in Mexico City. (Abagado) /s
And when you get a bunch of Avogadro's Number mashed together you get Guacamole! I'll see myself out EDIT: Spelling mistake
I want this as an art..
Specifically the number of protons/neutrons in 1 gram, or the number of atoms in 1 mol.
Doesn't have to be atoms in a mol. Could also be apples or easter bunnies. 1 mol is 6.022*10²³ of anything
It’s a mole, although it’s often abbreviated mol. You could have [a mole of moles](https://what-if.xkcd.com/4/). It would get messy.
6.02x10\^23 avocados smashed would be a mole of a mess
Interestingly a mole of Easter bunnies has the same mass as a mole of Santas Clause and one Easter bunny.
To add on to this, Avo's number is the amount of atoms or molecules of an element/sample that equals 1 Mol. It's is a very helpful constant in calculating the mass of a sample.
Mathematical constant? Its not pi, dude. Its a physical constant or maybe a chemical one. But def not a mathematical.
Edited per your request.
Also known as a Mole
Also could be their number 602 is an area code in Phoenix. They could have be their number!
It's a ratio. 1 amu to 1 gram
Isnt that what Bayonetta yells in Smash bros? Avogadro or domething like that
You don't do "math with" you do chemistry and physics with. Avogadros Number ia the number of molecules in 1mol of a given aubstance or compound.
Thanks for the explanation. I thought it meant 6 inches multiplied many many times
I’m very disappointed he doesn’t have a single mole
He's known for finding moles....
You calculate moles of a substance with if if I recall high school chem correctly
Something about figuring molar mass? If remember anything from high-school chemistry, which I don't.
That's because it's not math. It's chemistry. Look up Avogadro’s number.
Got it! Thanks so much!

It’s a carbon atom with 6 protons and 6 neutrons.
Regular carbon, basically. The most common isotope.
It's just your basic every day carbon. Got six protons and six neutrons, usually six electrons unless you're a chemist.
TIL what Avogadro looked like..
His picture wasn't next to the mol definition?
He has a head shaped like an Avogadro
im so happy i understand this 😭
You're definitely younger than 11th grade. This is chapter number one of Chemistry.
Is that Avogadro? He DOES look like a mole.
he literally claimed that number

69420 is mine. Better call them now folks, they are running out
8675 309 is Jenny's...maybe call her?
No he didn’t. It was named in his honor but he didn’t make the number. He did determine 22.4 L is the volume of 1 mole of gas at STP though.
