Question

vapour density of metal chloride is 77 . equivalent weight of metal is 3 , then its atomic weight will be​

Answer 1

Valency of metal is

Equivalent wt of metal+35.5

2×vapour density = 3+35.5

2×77 = 38.5

154 = 4.

The atomic weight of metal is equal to the product of the equivalent weight of metal and valency.

It is equal to 3×4=12.
