You're a smart guy. What do you think?

protons and neutrons happen to have a very consistent mass

atoms are made of consistent numbers of protons and neutrons such that every individual atom has a very predictable mass

if you have a gram of a pure element, then you should be able to describe how many atoms are present just by knowing the number of protons and neutrons in each atom, the mass of the protons and neutrons, and the total mass

6.02x10^23 just happens to be the constant that relates one gram of protons and neutrons to the number of protons and neutrons

well it's defined for carbon now but whatever

Considering 1 mole of a substance always has the same amount of grams as the individual atom/compound has amu, no it is not random.

It fits their equations because they pulled it out of their equations.

Moles?

>>8504645
I find we went to recalculate it with crystallography in a chemistry class.

6,02214179 x 10^23 atoms in a mole is not how a mole is defined, its a consequence of the definition of the mole

the mole is defined as the amount of atoms of carbon in 12 gramms of carbon 12, this ends up being this number, which they calculated by knowing that in one atome of carbon 12, you have 6 protons and 6 neutrons, knowing their masses, you know the mass of the atom (+ the mass of the 6 electrons which are quite irrelevant compared to the mass of the nucleons) and then you divide the 12 gramms by the mass of the atom, you get the number of atoms in these 12 gramms, nothing complicated seriously
