If the elevation in boiling point of a solution of 10g of solute (mol. Wt. = 100) in 100g of water is `DeltaT_(b)`, the ebullioscopic constant of water is

A

a) 10

B

b) 100Tb

C

c) `DeltaT_(b)`

D

d) `(DeltaT_(b))/(10)`

Text Solution

Verified by Experts

The correct Answer is:
C

`m=(1000xxk_(b)xxw)/(WxxDeltaT_(b))`
`DeltaT_(b)=(1000xxk_(b)xxw)/(Wxxm)`
`DeltaT_(b)=(1000xxk_(b)xx10)/(100xx100)`
`DeltaT_(b)=k_(b)`
