Question

The equivalent weight of an element is 4 it's chloride has vapour density 59.25 Then valency of elements is

Answer 1

It means that 4 grams of this element combines with 35.5 gram of Cl
Vapor density is 59.25
Molecular mass =2×VD
=118.5
Now since 4 grams of this element combines with 35.5 gram of Cl,they will always be in that package. Their combined weight will be 39.5.
118.5/39.5=3
Therfore the Valency is 3

Answer 2

here is your answer.....

remember :

$vapour \: density = \frac{molar \: mass}{2?}$
