If the elevation in boiling point of a solution of 10 g of solute (molecular weight = 100) in 100 g of water is `Delta T_(b)`, the ebullioscopic constant of water is

A

`10`

B

`100T_(b)`

C

`DeltaT_(b)`

D

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

Text Solution

Verified by Experts

The correct Answer is:
C
We know that,
`DeltaT_(b)=(1000xxK_(b)xxw)/(WxxM)`
`DeltaT_(b)=(1000xxK_(b)xx10)/(100xx100)=K_(b)`
