Following the synthesis and recrystallisation of aspirin, the purified crystals were collected and weighed.
The theoretical yield of aspirin for this preparation was 1.25 g. The actual mass of the recovered product was 1.45 g.
This resulted in a percentage yield greater than 100%.
Calculate the percentage yield of this reaction.
