3. A liquid mixture containing 45.0% benzene (B) and 55.0% toluene (T) by mass is fed to a distillation column. A product stream leaving the top of the column (the overhead product) contains 95.0 mole %B, and a bottom product stream contains 8.0% of the benzene fed to the column (meaning that 92% of the benzene leaves with the overhead product). The volumetric flow rate of the feed stream is 1000L/h and the specific gravity of the feed mixture is 0.872. Molecular weight of benzene is 78.11g/mol and MW of toluene 92.14g/mol. (a) Sketch a flowchart. (b) Determine the mass flow rate of the overhead product stream. (c) Determine the mass flow rate and composition (mass fractions) of the bottom product stream
