A liquid mixture of benzene and toluene contains 50.0% benzene by mass. The mixture is to be partially evaporated to yield a vapor containing 82.5% benzene and a residual liquid containing 20.0% benzene by mass. The process is carried out continuously and at steady-state. No reactions occur in the separator. The feed enters the separator at a rate of 100.0kg/h. Begin your analysis by drawing and labeling a flow sheet of the process and identifying all unknowns. How many independent balances may be written for the system? Solve for the liquid (L) and vapor (V) flow rates leaving the separator. V=L=kg/hkg/h
