Question

The equivalent mass of an element is $4$. Its chloride has vapour density $59.25$. Then the velocity of the element is:

Answer 1

Molecular weight of chloride $MC{l}_n$ $=59.25X2$ $=118.50$

Suppose atomic mass of $M=a$

$a+35.5n$ $=118.5$

$At.mass$ $=E $=EXn$

where n=valency or $Exn+35.5n$ $=118.5$

$n=4$

$4n+35.5n$ $=118.5$

$n=3$ is the answer.
