4-23. A mixture of ethanol (A) and water (B) is separated in a distillation column. The volumetric flow rate of the feed stream is 5 m'/hr. The concentration of ethanol in the feed is c 2,800mol/m. The distillate leaves the column with a concentration of ethanol c = 13,000 mol/m. The volumetric flow rate of distillate is one cubic meter per hour. How much ethanol is lost through the bottoms of the column, in kilograms of ethanol per hour?
