Compute the following for a case where the temperature is 85°F and the total pressure is 1 atm. a) The concentration (in ppm) of the saturated vapor with air above a solution of pure toluene. b) The concentration (in ppm) of the equilibrium vapor with air above a solution of 60 mol% toluene and 40 mol% benzene. c) The evaporation rate of the mixture (mg/min) in part (b) if the area for evaporation is 50 cm². d) What ventilation rate is required to keep the concentration below the TLV for the vapor in part (c) assuming the mixing is "average"? Comment on this flow rate - is it reasonable for a typical workspace?
