One thousand kilograms per hour of a mixture containing equal parts by mass of benzene and toluene are distilled. The flow rate of the overhead product stream is 488 kg/h and the bottom stream contains 7.11% wt benzene. Draw and label a flow chart of the process. THEN calculate the mass and mole fractions of benzene and the molar flow rates of benzene and toluene (mol/h) in the overhead product stream.
