The graph of temperature-component mole fraction for Benzene-Ethanol binary system is given in the picture. If you want to purify this binary mixture, which is known to have a 0.8 mole fraction, by simple (ordinary) distillation, what would the mole fraction of benzene in the distillate be approximately (but a reasonable value)?
