Benzene and toluene form nearly ideal so...

Benzene and toluene form nearly ideal solution. At `20^(@)C` the vapour pressure of benzene is 75 torr and that of toluene is 22 torr. The partial vapour pressure of benzene at `20^(@)C` for a solution containing 78g of benzene and 46 g of toluene in torr is-

A

`50`

B

`25`

C

`37.5`

D

`53.5`

Text Solution

Verified by Experts

The correct Answer is:
A
`P_(B)=P_(B)^(@)XB P_(B)^(@)=75` torr
`X_(B)=(78//78)/((78//78)+(46//92))=(1)/(1+05)=(1)/(1.5)P_(B)=75xx(1)/(1.5)=50` torr.
