5. In the recrystallization of acetanilide, water is an effective solvent for the purification, permitting easy removal of insoluble impurities, but it has the drawback that the difference between the solubility of acetanilide at \( 0^{\circ} \mathrm{C} \) and \( 100^{\circ} \mathrm{C} \) is not as large as desirable. These figures mean that a rather large volume of water is needed to dissolve the acetanilide and that a significant amount of product remains in the filtrate. a. If \( 2.0 \mathrm{~g} \) of crude acetanilide were obtained, how much boiling water would be necessary to dissolve the product? b. When this solution is cooled on ice, how much product would remain dissolved in solution? c. How much product would be left as a precipitate?
