1. 100 kmel mixture containing 35% ethanel (A) and 65% water (B) bx mole; It is heated and evaporated under differential conditions at a pressure of 101.32 kPa until 25 kmol is distilled. a. Find the composition of the liquid remaining at the end of distillation, b. Calculate the average composition of distilled steam (distillate)

Problem# 3: The leakage of hydrogen through a neoprene (vulcanized) tube that is 1.0 m long is 1.256 x 10-12 kmel at steady state. The hydrogen gas is flowing through the neoprene tube at 2.0 atm and 27 °C. The inside diameter of the neoprene tube is 3.0 mm. Calculate the outside diameter of the neoprene tube. (34 points)
