Q2 (25 pts). A liquid mixture composed of 40.0% ethylbenzene ( E ) and 60.0% xylene ( X ) by weight is introduced into a fractionating tower. A top product stream exiting the tower contains 90.0 mole\% E, and a bottom product stream contains 10.0% of the ethylbenzene fed to the tower (meaning that 90% of the ethylbenzene leaves with the overhead product). The feed stream has a volumetric flow rate of 2500L/h and the specific gravity of the feed mixture is 0.862 . Calculate the mass flow rate of the top product stream and the mass flow rate and composition (weight fractions) of the bottom product stream. a) Draw and label the flowchart, perform a degree-of-freedom analysis, and confirm that all unknown stream flows and compositions can be determined. b) Calculate the mass flow rate of the top product stream and the mass flow rate and mass fractions of the bottom product stream
