Question

one mole of chlorine combines with certain weight of metal giving 111gm of its chloride .The same amount of metal can displace,2gm hydrogen from an acid.The equivalent weight of metal is...
A)40
B)20
C)80
D)10​

Answer 1

Answer:

One mole of chlorine = 71 g.

Molecular weight of MCl

2

=111g

M+71=111

M=111−71=40

2g of H

2

is displaced by 40g of metal, then 1 g of H

2

is displaced by

2

40

=20 g of the metal.
