A student was synthesizing aspirin in the lab. Using the amount of limiting reactant, she calculated the mass of aspirin that should form as 5.24g. When she weighed her aspirin product on the balance, it mass was 2.23g. What is the percent yield of the aspirin?

Answer 1

The percent yield of aspirin can be calculated using the following formula:

Percent Yield = (Actual Yield / Theoretical Yield) × 100

Actual yield is the mass of the aspirin product obtained, which is 2.23g. Theoretical yield is the calculated mass of aspirin that should form, which is 5.24g.

Percent Yield = (2.23g / 5.24g) × 100 = 0.4255 × 100 = 42.55%

The percent yield of aspirin is 42.55%.
