The elevation in boiling point of a solu...

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
Molality =`13.44/134.4=0.1`
For `CuCl_(2)`,`i=3`
`DeltaT_(b)=i xx K_(b) xx m`
=`3 xx 0.52 xx 0.1`
=`0.156^(@)`
