What should be the boiling point of 1.0 ...

What should be the boiling point of `1.0 molal` aqueous `KCl` solution (assuming complete dissociation of KCl) if `K_(b)^(H_(2)O)` is `0.52 K m^(-1)`?

A

`100.52^(@)C`

B

`101.04^(@)C`

C

`99.48^(@)C`

D

`98.96^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
B
`DeltaT_(b)=iK_(b)m = 2 xx 0.52 xx 1 = 1.04(@)C`
rArr T_(b) = 100 + DeltaT_(b) =101.04^(@)C`
