At `88^(@)C` benzene has a vapour pressure of 900 torr and toluene has a vapour pressure of 360 torr. What is the mole fraction of benzene in the mixture with toluene that will boil at `88^(@)C` at 1 atm pressure? (Consider that benzene toluene form an ideal solution):

`0.416`

`0.588`

`0.688`

`0.740`
