A mixture containing 60 mol % benzene and 40 mol %

A mixture containing 60 mol % benzene and 40 mol % toluene is subjected to simple batch distillation at 1 atm. The process is carried out until an average distillate composition of 70 mol % benzene is obtained. Assuming constant relative volatility of 2.43, determine the total moles of distillate for 100 mole of feed and the composition of the residue in the still pot
