A certain hydrate has the formula "MgSO"...

A certain hydrate has the formula `"MgSO"_(4).xH_(2)O`. A quantity of 54.2 g of the compound is heated in an oven to drive off the water. If the steam generated exerts a pressure of 24.8 atm in a 2.0 L container at `120^(@)C`, calculate `x`.

Text Solution

Verified by Experts

The correct Answer is:
d
(d) `n_(H_(2)O)=(PV)/(RT)=1.54`
`(n_(MgSO_(4))xxH_(2)O)/n_(H_(2)O)=(1)/(x)=(54.2)/(120+18x)xx1.54`
`x=7`
