Avogadro's number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro's number. To convert from atoms to moles, divide the atom amount by Avogadro's number (or multiply by its reciprocal).

A mole is just a number, like a "dozen" eggs is 12 eggs. One mole corresponds to Avogadro's number, 6.02x10^23. In chemistry, one mole of a substance means that there are 6.02x10^23 of those molecules present. A molecule is one, single, individual specimen of a compound.

Avogadro's number is an absolute number: there are 6.022×1023 elementary entities in 1 mole. This can also be written as 6.022×1023 mol-1. The mass of one mole of a substance is equal to that substance's molecular weight.
1412963
One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions).

In order to work this out, multiply Avogadro's number - the one I stated at the start of this explanation - by 2 . This will give you the number of molecules in 2 moles of a substance. In other words, 1 mole of atoms is 6.02×1023 atoms. 1 mole of molecules is 6.02×1023 molecules.

The number of atoms of ANY substance in a volume is: # of atoms = N * (density) * volume / (Molecular Weight). N is a constant called Avogadro's number and its equal to 6.022*1023 atoms/mole. It can also be molecules per mole.

, double the number of atoms, because there are 2 atoms per molecule. Remember, one mole of something is 6.022 X 1023 of whatever it is. If it is molecules, it's 6.022 X 1023 of them. If it is atoms, it's 6.022 x1023 atoms.
