A solution contains 15% A by mass (XA = 0.15) and 20 mole% B (YB = 0.20). (Note: If a mass or molar unit is not followed by the name of a specie, the unit refers to the total mixture or solution rather than to the specific component). a. Calculate the mass of A in 175 kg of the solution. b. Calculate the mass flow rate of A in a stream of the solution flowing at a rate of 53 lbm/h. C. Calculate the molar flow rate of Bin a stream flowing at a rate of 1000 mol/min. d. Calculate the total solution flow rate that corresponds to a molar flow rate of 28 kmol B/s. e. Calculate the mass of the solution that contains 300 lbm of A
