Hi Nicole H.,

The "common currency" for all such chemistry questions is moles! Convert each element into moles, by dividing by the atomic mass (the Periodic Chart gives you nuclei average mass, but that's essentially the value you use for the whole atoms as well). Then multiply by You-Know-Whose Number to get numbers of atoms.
