Y g of non-volatile or ganic substance of molecular mass M is dissolved in 250 g benzene. Molal elevation constant of benzene is `K_(b)`. Elevation in its boiling point is given by :

A

`M/(K_(b)Y)`

B

`(4K_(b)h)/M`

C

`(K_(b)y)/(4M)`

D

`(K_(b)y)/M`

Text Solution

Verified by Experts

`DeltaT_(B)=mk_(B)" "=hxx1000xxK_(b)`
`M xx 250" "impliesDeltaT_(b)=(4_(y)K_(b))/M`
