A mole of ANYTHING contains Avogadro's number of particles, which is 6.02x10^23 of them. So if 1 mol of gold =6.02x10^23, then 3.21 mol of gold will have: 3.21mol x (6.022x10^23 atoms/mol)=...atoms of gold

To find out how many atoms in any amount of a substance you need to
1. Remember that 1 mole of any substance contains 6.023 atoms
2. Mutiply the number of moles by 6.023
3.21*6.023=19.34 atoms

thats very simple if you know the method
1mole of gold = atomic mass in grams = avogadro"s number
so
avogadro number x 3.21 = xxxxxxx atoms

1 mol of anything is 6.022x10^23 so 3.21 moles of gold would be
3.21molesx(6.22x10^23)=#of moles of gold
