A 40 kmol liquid mixture containing 60% n-pentane and 40% n-heptane is distilled under differential conditions until 34% n-pentane remains in the liquid in the boiler. Calculate the amount of distillate obtained at the end of the process and the average concentration of the distillate. Note: Relative volatility 3 can be taken for this mixture
