Ok , so basically, 1 mole of ammonium phosphate(molecules) has 12 moles of hydrogen(atoms). We need to find out how much ammonium phosphate has 3.18 moles of hydrogen .
Simple , Unitary method. We find that 0.265 moles of ammonium phosphate has 3.18 moles of hydrogen. We also know that 1 mole of ammonium phosphate has 4 moles of oxygen. Again, using the Unitary method , we find that 0.265 moles of ammonium phosphate has 1.06 moles of oxygen .

→ 1 mole of (NH4)3PO4 will contain 12 mole H- atom
→ So, 3.18 mole of H-atom will be present in
→ 1/12 × 3.18 moles of (NH4)3PO4
= 0.265 moles of (NH4)3PO4
→ 1 mole of (NH4)3PO4 contains 4 moles of H-atom.
→ So, 0.265 (NH4)3PO4 will contain
→ 4×0.265 = 1.06 moles of oxygen atoms.
