Acetone is used in the manufacture of many chemicals and also as a solvent. In its latter role, many restrictions are placed on the release of acetone vapor to the environment. You are asked to design an acetone recovery system having the flowsheet illustrated in Figure. All of the concentrations shown in Figure of both the gases and liquids are specified in weight percent in this special case to make the calculations simpler. Calculate A$,$ F$,$ W$,$ B$,$ and D in kilograms per hour. Assume that $G=1000k\frac{g}{h}r.$
