Question

Q.
The atomic mass of a metal (M) is 27 and its equivalent
mass is 9, the formula of its chloride will be:
(a) MCI. (c) M3C14
(b) MCl9. (d) MC13



​

Answer 1

Atomic weight = Equivalent weight x valency

Given :

Atomic weight = 27

Equivalent weight = 9

Valency = 27/9 = 3

Valency of M is 3 . By cross over the formula will be MCl3.
