Final answer:
The corrected yield of a substance is calculated by adding the actual yield to the amount of the substance remaining in the solution when the crystals formed.
Step-by-step explanation:
To determine the corrected yield of a substance, including the amount left in solution when crystals formed, use the formula:
Corrected Yield = Actual Yield + Amount of Aspirin in Solution
This calculation takes into account both the isolated product and the product which remains dissolved in the solution, providing a more complete picture of the reaction's efficiency.
