Question

What is the percent yield of a chemical reaction if 50 grams of reactant A were used and 35 grams of product B were obtained, given that the balanced equation for the reaction is:2A + 3B --> 4Cand the theoretical yield of product B is 45 grams?

Answer 1

Percent yield is calculated using the formula:Percent yield =  Actual yield / Theoretical yield   100In this case, the actual yield of product B is 35 grams, and the theoretical yield is 45 grams. Plugging these values into the formula:Percent yield =  35 grams / 45 grams   100Percent yield = 0.7778  100Percent yield = 77.78%The percent yield of the chemical reaction is 77.78%.
