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

`0.01 K//m`

B

`0.1K//m`

C

`1K//m`

D

`10 K//m`

Text Solution

Verified by Experts

Molality `=(w_(1)xx1000)/(m_(1)xxw_(2))`
`=(1.8xx1000)/(180xx100)=0.1`
`DeltaT_(b)=K_(b)xxm`
`:.K_(b)=(DeltaT_(b))/(m)=(0.1)/(0.1)=1km`
