Question

What is the yield of acetylsalicylic acid produced when 5 grams of salicylic acid is reacted with excess acetic anhydride, assuming a theoretical yield of 7 grams and an actual yield of 4.5 grams?

Answer 1

To calculate the percent yield of acetylsalicylic acid, we can use the formula:Percent Yield =  Actual Yield / Theoretical Yield   100Given the actual yield is 4.5 grams and the theoretical yield is 7 grams, we can plug these values into the formula:Percent Yield =  4.5 grams / 7 grams   100Percent Yield = 0.642857  100Percent Yield  64.29%The yield of acetylsalicylic acid produced in this reaction is approximately 64.29%.
