The weight of `1xx10^(22)` molecules of `CuSO_(4).5H_(2)O` is

A

`41.59 g`

B

`415.9 g`

C

`4.159 g`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C
Mol. Mass of `CuSO_(4).5H_(2)O`
`=63+32+16xx4+5xx18=249`
`6.02xx10^(23)` molecules of `CuSO_(4).5H_(2)O` has a mass
`=((249g)xx1xx10^(22))/(6.02xx10^(23))=4.159g`
