At `334K` the vapour pressure of benzene`(C_(6)H_(6))`is`0.526`atm and that of toluene`(C_(7)H_(8))`is`0.188`atm. In a solution containing`0.500`mole of benzene and`0.500`mole of toluene , what is the vapour pressure of toluene above the solution at`334K` ?

A

`0.188`atm

B

`0.10`atm

C

`0.357`atm

D

`0.094`

Text Solution
