Question

What is the percent yield of a chemical reaction when 5 grams of reactant A reacted with excess reactant B to produce 3.5 grams of product C, given that the theoretical yield of C is 4 grams?

Answer 1

The percent yield of a chemical reaction can be calculated using the following formula:Percent Yield =  Actual Yield / Theoretical Yield   100In this case, the actual yield is 3.5 grams of product C, and the theoretical yield is 4 grams of product C. Plugging these values into the formula:Percent Yield =  3.5 / 4   100 = 0.875  100 = 87.5%So, the percent yield of the chemical reaction is 87.5%.
