This compound is ammonium sulfate

The properly formatted depiction of its formula is

(NH4)2SO4?

The Relative atomic mass of its constituent atoms are listed and multiplied by the number of atoms in the molecule.

N=14.01 ; 14 * 2 =     28.02

H=1.01; 1.01 * 4 * 2 = 8.08

S=32.07; 32.07 * 1=  32.07

O=16; 16 * 4 =          64

The composite products are summed to yield the total Relative atomic mass.

28.02 + 8.08 + 32.07 + 64 = 132.17 (amu)
