How to use

Percent yield

$$%;\text{yield} = 100 \times \frac{\text{actual}}{\text{theoretical}}$$

  • Actual is what you isolated; theoretical is the stoichiometric ceiling.
  • Use the same unit for both (g with g, or mol with mol).

When to use

  • Lab reports and comparing routes or batches.
