1. mols Cu in 5 g Cu = 5.00/63.55 = ??
# atoms in that many mols Cu will be the same for ANY monatomic element.
If you want the grams of Na in this amount, then mols = g/atomic mass OR
g = mols x atomic mass = ??mols x 23 (Look up the atomic mass of Na to make sure that is right).

2. question is confusing. Is the answer 2.1789 mol of Na?

3. No. Re-read my response. It clearly says
mols Cu = 5.00/63.55 = ?? and that will be the mols Na or any other monatomic element of your choosing. Punch in 5.00 and divide by 63.55 and I don't get 2.17
