Explanation:

(NH4)2SO4   Molar weight (from periodic table)

       (N =14    H4 = 4   ) * 2 = 36

           S = 32   O4 = 64                  TOTAL = 132 gm/mole

N % =  ( 2*14) / 132 = 21.2%       molar mass = 28 gm

H % = (2 *4) / 132 =  6%            molar mass = 8  gm

S % =  32/132 = 24.2 %             molar mass = 32 gm

O % = (64) / 132 = 48.5%           molar mass = 64  gm
