The solubility of a gas in a liquid is unrelated to the pressure of the gas above the liquid directly proportional to the pressure of the gas above the liquid proportional to the square root of the pressure of the gas above the liquid inversely proportional to the pressure of the gas above the liquid description

Liquid from a brewery fermentation contains 10% ethanol and 90% water. part of the fermentation product (50,000 kg/h) is pumped to a distillation column on the factory site. under current operating conditions, a distillate of 45% ethanol and 55% water is produced from the top of the column at a rate of one-tenth that of the feed. what is the composition of the waste "bottoms" from the still?
