A gas stream contains 21.0 mole\% hexane and the remainder nitrogen. The stream flows to a condenser, where its temperature is reduced and some of the hexane is liquefied. The hexane mole percent in the gas stream leaving the condenser is 2.00. Liquid hexane condensate is recovered at a rate of 2.00L/min. You may take the specific gravity of liquid hexane to be 0.6548. What is the flow rate of the gas stream leaving the condenser in mol/min ? mol/min What percentage of hexane entering the condenser is removed as a liquid? %
