Q: The equivalent weight of an element is 4 . Its chloride has a vapour density 59.25. Then the valency of the element is

(A) 4

(B) 3

(C) 2

(D) 1

Ans: (B)

Sol: Molecular weight of MClx = 2 x 59.25 = 118.5

$\large Equivalent \; weight = \frac{Molecular \; weight}{x}$

$\large Equivalent\; weight of (M+Cl) = \frac{Molecular \; weight}{x}$

$\large x = \frac{Molecular \; weight}{4+35.5} = \frac{118.5}{4+35.5} = 3$
