Expert Answer:


Formula of ammonium sulphate is (NH4)3 PO4

 12 mole of H atoms are present in 1 mole (NH4)3 PO4

Therefore 3.18 mole of H atoms are present in 0.265 mole (NH4)3 PO4

 1 mole (NH4)3 PO4 contains 4 mole of oxygen atoms

Therefore 0.265 mole  (NH4)3 PO4 contains 1.06 mole of oxygen atoms
