The rise in boiling point of a solution ...

The rise in boiling point of a solution containing `1.8g` glucose in `100g` of a solvent is `0.1^(@)C`. The molal elevation constant of the liquid is-

A

`0.01K//m`

B

`0.1K//m`

C

`1K//m`

D

`10K//m`

Text Solution

Verified by Experts

The correct Answer is:
D
`DeltaT_(b) = K_(b) xx m`
`K_(b) = (DeltaT_(b))/(m) = 0.1 xx (180)/(1.8) = (0.1)/(0.01) = 10`
