M[(NH₄)₂SO₄]=2A(N)+8A(H)+A(S)+4A(O)

M[(NH₄)₂SO₄]=2·14.0+8·1.0+32.1+4·16.0=132.1 g/mol

Answer:

  • The formula mass of (NH4)2SO4 is 132.06 g/mol

Formula mass = 2×(Atomic mass of N)+ 8× (Atomic mass of H)+ (Atomic mass of S) +                       4×(Atomic mass of O)


Formula mass =  2 (14) + 8×(1.008) + (32) + 4 ×(16)

Formula mass = 132.06 g/mol
