# Calculating Percent Yield of Aspirin Product

## Explanation:

**To calculate the percent yield of the aspirin product**, you would use the actual yield and the theoretical yield. The percent yield is found by dividing the actual yield by the theoretical yield and then multiplying the result by 100. So for an actual yield of 4.28 g and a theoretical yield of 5.46 g, the calculation would be:

(Actual yield / Theoretical yield) Ã 100 = (4.28 g / 5.46 g) Ã 100

This gives us: (4.28 g / 5.46 g) Ã 100 = 78.39%

Therefore, the percent yield of the aspirin product is approximately 78.40%, which would be option a).
