Expert Answer
Given:
Vapour density of metal chloride = 77
Molecular weight = 2 × 77 = 154 ..... (1)
Let the valency of element is x.
Atomic weight = Equi. wt × Valency
= 3× (x)
The formula of chloride is MClx
Mol. wt of chloride = 3x + 35.5x = 38.5x .... (2)
From eq(1) and (2)
38.5x = 154
x = 4
Atomic weight = 4× 3
= 12
