i need help with this question in details, many thanks

Problem 3: 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 vapour to the environment. You are asked to design an acetone recovery system having the flowsheet illustrated as below. All the compositions shown in the below figure of both gases and liquids are specified in mass fraction. Calculate the individual component mass flow rates and total mass flow rates for all streams and write your results into the attached table. Air A (kg/h)??? Air: 0.995 Water: ??? Water W(kg/h) ??? D(kg/h) ??? Acetone: 0.98 Water: ??? ABSORPTION COLUMN DISTILLATION COLUMN Feed F = 7500 (kg/h) Air: 0.95 Acetone: 0.03 Water: ??? S(kg/h)??? Acetone: 0.19 Water: ??? B (kg/h) ??? Acetone: ??? Water: 0.96 Table of mass balance, the individual component mass flow rates (kg/h) Streams F w S D B Air (kg/h) Acetone (kg/h) Water (kg/h) Tng (kg/h) 7500
