The weight of `1 xx 10^(22)` molecules of `CuSO_(4). 5H_(2)O` is

A

`4.144 g`

B

`5.144 g`

C

`6.144 g`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
Mol.wt.of `CuSO_(4).5H_(2)O=249.6`
`:.` Mass of `1xx10^(22)` molecules
`=(249.6xx110^(22))/(6.023xx10^(23))=4.144 g`
