AActual yield divided by theoretical yield, times 100
BTheoretical yield divided by actual yield, times 100
CActual yield divided by mass of reactants, times 100
DMass of product divided by mass of solvent, times 100
Answer & Solution
Correct answer: A. Actual yield divided by theoretical yield, times 100
1. Percent yield measures how much of the predicted product was really obtained.
2. So the actual yield goes on top and the theoretical yield underneath.
3. Multiplying that fraction by 100 turns it into a percentage.
4. Both yields must be in the same units so that the units cancel.
