A student performed a recrystallization of a sample of impure benzoic acid. From an original 5.00g sample, the student recovered 3.78 g of material. The melting point of the recovered sample was measured to have a range of 118.9C122.5C The literature melting point for benzoic acid is 122.3C. a. Calculate the % recovery of recrystallized benzoic acid. (5 points) b. Does the melting point data indicate that the recrystallized material has been purified? Explain. (5 points)
