A sulphate of a metal is isomorphous with `ZnSO_(4)*7H_(2)O`. In this salt, the percentage of the metal is 9.75. what is the atomic mass of the metal?

Text Solution

Verified by Experts

The metallic sulphate is isomorphous with `ZnSO_(4)*7H_(2)O`
Let, the atomic mass of the metal be x,
`therefore`molecular mass of `M=x+32+64+126=x+222`
Metal present in `MSO_(4)*7H_(2)O` is 9.75%.
`(x)/(x+222)xx100=9.75" "therefore x=23.98`
