The vapour pressure of hexane`(C_(6)H_(14))` and heptane`(C_(7)H_(16))` at `50^@C` are 408 torr and 141 torr, respectively, The composition of the vapour above a binary solution composition a mole fraction of `0.300` hexane is `(y_(6)`=mol fraction of hexane and `y_(7)`=mol fraction of heptane)

The vapour pressure of pure benzene and toluene at 40^(@)C are 184.0 torr and 59.0 torr, respectively. Calculate the partial presure of benzene and toluene, the total vapour pressure of the solution and the mole fraction of benzene in the vapour above the solution that has 0.40 mole fraction of benzene. Assume that the solution is ideal.

The vapour pressures of pure liquids A and B respectively are 600 torr and 500 torr. In a binary solution of A and B , mole fraction of A is 0.25 then total pressure of the solution (in torr) will be
