Question

Mg3 N2 calculate the molecular mass​

Answer 1

Atomic mass of Mg = 24

Atomic mass of N = 14

MOLECULAR  MASS = 24×3+14×2

                                  = 72+28

                                   = 100 u

Answer 2

molecular mass of magnesium is=24 andnitrogen is 14

24+24+24+14+14=100

so molecular mass of compound is 100
