What This Actual Yield Calculator Helps You Do
This page keeps yield calculations transparent by connecting the bench result back to stoichiometric theory. That makes it easier to discuss efficiency, purification losses, and whether a reaction scaled the way you expected.
It also supports the reverse calculation for percent yield so you can compare experimental runs quickly without rearranging the equation by hand.
How to Calculate Actual Yield Calculator
- Choose the yield task: Solve for actual yield or percent yield depending on the information you already have.
- Use consistent units: Theoretical and actual yield must use the same mass or mole unit.
- Check that theoretical yield is positive: Percent-yield formulas only make sense when the stoichiometric maximum is greater than zero.
- Interpret the percentage: Percent yield helps you compare process efficiency across experiments or batches.
Actual Yield Calculator Formula
| Variable | Meaning | Unit |
|---|---|---|
| Actual yield | The amount of product isolated from the real experiment | same as theoretical yield |
| Theoretical yield | Maximum possible product from stoichiometry | g, mol, or any consistent unit |
| Percent yield | Actual yield as a percentage of theoretical yield | % |
Use the worked examples below to check how the formula behaves with real values. If the result looks unexpected, verify the unit assumptions and the meaning of each variable before interpreting the answer.
Worked Examples
- Theoretical yield: 80 g
- Percent yield: 75%
Result: Actual yield = 80 × 75 / 100 = 60 g.
A 75% yield means one quarter of the theoretical maximum was not isolated as final product.
- Actual yield: 60 g
- Theoretical yield: 80 g
Result: Percent yield = 60 × 100 / 80 = 75%.
Percent yield is a compact way to compare reaction performance across runs.
How to Interpret Your Results
| Range | Meaning | Action |
|---|---|---|
| Below 50% | A large share of the theoretical product was lost or never formed. | Review side reactions, workup losses, and limiting-reagent assumptions. |
| 50% to 90% | A moderate to good practical yield. | Benchmark against similar reactions and purification steps. |
| Above 90% | Very efficient isolation or formation relative to theory. | Double-check measurement accuracy and purity assumptions. |
