(I)   2 g of hydrogen
       number of moles = $\frac{2}{1}$ = 2 × N_A number of atoms
(II)   6 g of sulphur
       number of moles = $\frac{16}{32} = \frac{1}{2}$ × N_A number of atoms
(III)  4 g of oxygen
       number of moles = $\frac{4}{16} = \frac{1}{4}$ × N_A number of atom
(IV) 31 g of phosphorus
       number of moles = $\frac{31}{31}$ = 1 × N_A number of atoms
