Homework Help: Chemistry

Posted by Nat on Monday, November 22, 2010 at 8:11am.

You have 150 ml of a solution of benzoic acid in water estimated to contain about 5 g of acid. The distribution coefficient of benzoic acid in benzene and water is approx 10. Calculate the amount of acid that would be left in the water solution after three 50 ml extractions with benzene. Do the same calculation using one 150 ml extraction with benzene to determine which method is more efficient.

My ans:
k = (concentration of benzoic acid in benzene)/(benzoic acid conc in water) = 10

But I am not sure how to proceed from this. Any help appreciated
