Consider a situation where 1.5 grams of benzoic acid is dissolved. Use the value 332.5 for the distribution coefficient, Kd, and calculate how much benzoic acid would remain in the aqueous phase after 2 extractions with 30 mL of ether. What percentage of the original benzoic acid was extracted into the ether phase? Is a single extraction with 60 mL ether or 2 extractions with 30 mL ether more efficient?

I meant Kd = 3.325****
