    The Limiting Reagent and Percent Yield

    I need helping with how to determine a limiting reagent and percent yield. For the following question, I started out with 0.60 grams of trans-cinnamic acid and added 3.5 mL of dichloromethane and 2.0 mL of 10% bromine in dichloromethane solution. I re-fluxed the reaction, and, during re-fluxing, added a couple more drops of the
