On heating `100g` of `Na_(2)SO_(4) 10 H_(2) O` will loose ..... % of water.

A

`44.1`

B

`65.3`

C

`55.9`

D

`34.7`

Text Solution

Verified by Experts

The correct Answer is:
C
It is equal to the mass precent of wate.
Percent water
`= ("Mass of" H_(2) O "in 1 mol of compound")/("Molar mass of compound") xx 100%`
`= (180)/(320) xx 100% = 59.9%`
