A mixture containing 45 wt% benzene and 55 wt% toluene is fed to a distillation column. An overhead stream of 95 wt% benzene is produced, and 8.0 % of the benzene fed to the column leaves in the bottom stream. The feed rate is 2,000 kg/hr. Determine the overhead mass flow rate and mass flow rates of benzene and toluene in the bottom stream. What is the molar flow rate of the feed stream to the column?
