One Sulphate molecule contains 5 atoms, one of sulphur and 4 of oxygen.
hydrogen is not a molecule.
One atom per molecule.
Lithium Sulfate Li2SO4 has 4 oxygen atoms per molecule.
Only one per molecule of Ammonium Sulphate. The fornula is NH3SO4
A molecule is a combination of atoms. To know how many atoms are in one molecule, you have to find out what atoms are in the molecule.
I think there is one atom of copper and four atoms of sulfur but you should get a second opinion. I am 98% sure this is correct.
