If the percentage of water of crystallization in `MgSO_(4) .x H_(2)O` is `13%`. What is the value of `x` :

A

`1`

B

`4`

C

`5`

D

`7`

Text Solution

Verified by Experts

The correct Answer is:
A
`%` by wt of `H_(2)O`
`("wt.of" H_(2)O)/("Total wt.of compound")xx100`
`13 = (18x)/(18x + 120) xx 100`
`x = 1` .
