Suppose you have been given the task of distilling a mixture of
hexane + toluene. Pure hexane has a refractive index of 1.375 and
pure toluene has a refactive index of 1.497. You collect a
distillate sample which has a refractive index of 1.441. Assuming
that the refractive index of the hexane + toluene mixture varies
linearly with mole fraction, what is the mole fraction of hexane in
your sample?
Calculate the equilibrium vapor phase composition of a liquid hexane–water mixture at 50 °C, assuming that hexane and water are completely immiscible. The vapor pressures of the pure components can be described by the Antoine equation:

The vapor pressures of benzene and toluene at 95◦C are,
respectively, 155.7 kPa and 63.3 kPa. A gaseous mixture consisting
of 50 moles of benzene and 50 moles of toluene was cooled to 95◦C.
As a result of the cooling, some of the benzene and toluene
condensed. If the total pressure above the condensate was 101.3
kPa, calculate:
