Theoretical Yield: 10 mmol (.010 mol) X 150.2 g/mol = 1.50 g Acetylanisole Weight(crude) of product after rotovap: 0.36 g Recovered product after distillation: 0.35 g Percent Yield: 0.35 g/ 1.50 g X 100 = 23.3 % **Total product recovered is a result of adding individual results to three other lab partners solutions for the distillation process to achieve greater results** Boiling Range: 130C- 135C **
