the molecule is Ca3(PO4)2, which is Ca3P2O8
That tells you how many atoms in each molecule, so it is the same as the ratio of moles
Consider calcium phosphate.
1) How many moles of calcium atoms are present in one mole of calcium phosphate?
2) How many moles of phosphorus atoms are present in one mole of calcium phosphate?
3) How many moles of oxygen atoms are present in one mole of calcium phosphate?

Ca3(PO4)2.
Look at the formula above. You can see for 1 mol Ca3(PO4)2 you have 3 mols Ca, 2 mols P and 8 mols O and 2 mols of PO4^3-.
