The elevation in boiling point of a solution of `13.44`g of `CuCl_(2)`(molecular weight =`134.4,k_(b)=0.52K "molality"^(-1))` in `1` kg water using the following information will be:

A

`0.16`

B

`0.05`

C

`0.1`

D

`0.2`

Text Solution

Verified by Experts

The correct Answer is:
A
`DeltaT_(b)=i K_(b) m ` `i`(vant Haff factor) of `CuCl_(2)=3`
`DeltaT_(b)=3xx0.52xx(13.44)/(134.4xx1)=0.156=0.16`.
