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
[`:'` Molecular weight of `CuSO_(4).5H_(2)O`
`=63.5+32+64+90=249.5]`
`6xx10^(22)` molecules has weight`=249 g`
`1xx10^(22)` molecules has weight`=(249.5xx1xx10^(22))/(6xx10^(23))`
=`4.8xx10-1=4.158`
