please show work step by step, clear and neat. i will give good rate

Fifty pounds of an acetone-water solution containing 10 % acetone by mass is to be produced in an absorption column. An acetone-air mixture containing 20 % acetone by mass is fed to the column and the acetone is scrubbed from the air by water fed to the top of the column. The acetone in the exit gas stream is 3 % acetone by mass (1) (11) Draw a flow chart (Block flow diagram) of the absorption column Calculate the amount of acetone-air mixture fed to the column, stating all assumptions
