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.

A mole of a compound will have 6.02 x 10^23 molecules, so the number of atoms in a mole is 6.02 x 10^23 x number of atoms in a molecule. One Molecule of Ca(OH)2 has 5 atoms. Therefore, one mole of Ca(OH)2 has 6.022 x10^23 x 5 = 30.11 x 10^23 atoms.

If we have 2 mol of Na atoms, we have 2 × (6.022 × 10 23) Na atoms, or 1.2044 × 10 24 Na atoms. Similarly, if we have 0.5 mol of benzene (C 6H 6) molecules, we have 0.5 × (6.022 × 10 23) C 6H 6 molecules, or 3.011 × 10 23 C 6H 6 molecules. A mole represents a very large number!

By looking at a periodic table, we can conclude that the molar mass of the element lithium is 6.94g, the molar mass of zinc is 65.38g, and the molar mass of gold is 196.97g. Each of these quantities contains 6.022×1023 atoms of that particular element. The units for molar mass are grams per mole or g/molg/mol.
