(3] A mixture of 40 mol% benzene and 60 mol% toluene is subjected to a simple batch distillation at atmospheric pressure. If the distillation is discontinued when the moles of distillate amount to 65% of the moles charged. Average relative volatility, a = 2.5. Calculate (i) the concentration of the liquid left in the still, (ii) the concentration of the distillate, (iii) the amount of benzene in the distillate expressed as %-age of Benzene amount in the original charge.
