Assume you have a 10 gram mixture of A and B in a 9:1 ration of A to B and that both have a solubility at room temperature of 0.04 g/mL. If you used 20 mL of solvent for recrystallization, how much B would be expected to be in the crystallized material? What is the ration of A:B in the crystalized material?
