Problem- A sample contains 132 mg of compound A along with 24.0 mg of impurity B. The solubility of compound A in water at 25 oC is 14.0 mg/ml, and at 100 oC is 110 mg/ml. The impurity B has the same solubility behavior as compound A in water. A) By showing all the calculations, describe how you would purify the sample. B) How many steps of crystallization you needed to do to get pure compound A? C) What is the amount of pure compound A after all crystallization steps? D) Calculate the percent recovery of pure compound A after all the crystallization st
