A liquid mixture is fed to a distillation column. It contains 60% toluene and 40% benzene by mass. The bottom product stream comprises of 10% of the net benzene fed to the column. The overhead (top) stream comprises of a mixture with 90 mole % benzene. The density of the feed mixture is 0.8 kg/L and the feed flow rate is 2500 L/h. Determine the mass flow rates and composition (mass fractions) of all the streams (feed, bottom and overhead).
