A balloon filled with 0.427 L of air at sea level is submerged in the water to a depth that produces a pressure of 4.49 atm. What is the volume (in L) of the balloon at this depth? Hint: Think about the pressure at sea level (the surface)

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?
