a Question 1: (30 points): A solvent containing 10% by weight acetone and 90% by weight chloroform is used to extract acetone from a feed containing 55 wt% acetone and 5 wt% chloroform with the remainder being water. The feed rate is 250 kg/hr, while the solvent rate is 400 kg/hr. Operation is at 25C and atmospheric pressure.
