The percentage of water in `CuSO_(4) . 5H_(2)O` is

A

36

B

12

C

25

D

60

Text Solution

Verified by Experts

The correct Answer is:
A
Molar mass of `CuSO_(4) . 5H_(2) = 249.5 g`
`[CuSO_(4) . 5H_(2)O = 63.5 + 32 + 64 + 5 xx 18 = 249.5]`
`therefore` In 249.5 g `CuSO_(4).5H_(2)O`
Water = 90 g
`therefore` In 100 g `CuSO_(4). 5H_(2)O`,
Water = `(90 xx 100)/(249.5) = 36%`
