Calcium sulfide CaS has two atoms. Two fluorine atoms. CaCO3 1 Calcium atom 1 Carbon atom 3 oxygen atoms total 5 atoms. The formula unit for calcium nitride is Ca3N2. That would be 3 atoms of calcium and 2 atoms of nitrogen, for a total of 5 atoms in a formula unit.

Chemists define a mole of a compound as Avogadro's number of molecules of that compound. You can use this information to calculate the number of moles in a sample of a compound with a known weight or mass. Conversely, if you know the number of moles of the compound you have, you can calculate the weight or mass of the sample. These calculations apply whether the compound is a solid, liquid or gas, but to perform either of them, you need to know the molecular mass of the compound. As long as you know the chemical formula of the compound, you can look up its molecular mass. To find the number of moles of a compound you have on hand, look up the molecular weight of the compound and divide that number into the weight you have on hand.
