2) (4 pt) After the reaction was completed, the student collected the following data. Crude product data is the data collected after the reaction is finished, but before the product is purified. "Pure" product data is the data collected after attempted purification using recrystallization. Student B's data: Crude product data "Pure" product data after recrystallization Crude mass: 0.93 g grey solid Crude mp: 96-106 °C Crude % yield: Pure mass: 0.39 g white solid Pure mp: 111-113 °C Pure % yield: a) Calculate the crude and pure percent yields for the student's reaction. b) Summarize what is indicated by the crude and pure melting points.
