Question

molecular mass of zncl2

Answer 1

Here molecular mass of zinc is 65.38 and the molecular mass of chloride is 35.5 since there are two molecules so molecular mass of two molecules of chloride will be 71 so total molecular mass of zinc chloride will be 65.38+71 will be 136.38

Answer 2

Molecular mass of zinc is 65 molecular mass of chlorine is 35u
Molecular mass of zinc chloride ( ZnCl2) = 65 + 35x2
= 65 + 70 = 135 u
