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

`(DeltaT_b)/(10)`

B

`DeltaT_b`

C

`10DeltaT_b`

D

`1000DeltaT_b`

Text Solution

Verified by Experts

The correct Answer is:
B
`m= (1000xx K_bxxw)/(wxxDeltaT_b)`
Or `K_b = (mxx WxxDeltaT_b)/(1000xx10)`
`= DeltaT_b`
