How do I calculate the number of atoms in a compou

posted by .

I have the mass of the amount of substance, and the molar masses. How do I do this? Is this the same as calculating the number of molecules/ formula units? Also, I know the number of atoms for each element in the compound (It made me calculate that before)

    You don't have all of the information for me to answer. Why not type specific question and tell us what you don't understand about it.\
    mols = grams/molar mass
    # molecules = mols x 6.02E23
    # atoms = #molecules x (#atoms/molecule)
