One thousand kilograms per hour of a mixture of benzene (B) and toluene (T) containing 50% benzene by mass is separated by distillation into two fractions. The mass flow rate of benzene in the distillate stream is 400 kg B/h and that of toluene in the bottom stream is 450 kg T/h. The operation is at steady-state. Total flow rate of distillate is ____kg/h and the mass fraction of toluene in the bottoms is ____.
Hint: Perform Benzene material balance and toluene material balance. Perform overall material balance to determine distillate flow rate and bottoms flow rate. Knowing total bottoms flow rate and flow rate of toluene in that stream, you can determine the fraction.
