Percent yield is always used to evaluate the efficiency of a synthetic reaction. This is also the ultimate goal for making the reagent table - because we need to know how much product has been produced from a certain amount of reactants, and this will tell us the best condition (out of a series of experiments, of course). In fact, for a reaction: a. We first figure out the mole of the limiting reagent (because mole tells the number of molecules, grams and milliliters don't). b. From the limiting reagent, we can come up with the theoretical yield. C. Then we use the mole of the actual product divided by the theoretical yield and times 100% to get the % yield.
