What to enter
| Input | Meaning and units |
|---|---|
| Actual product mass (g) | Enter actual product mass in g; use the same basis as the other measurements. |
| Theoretical product mass (g) | Enter theoretical product mass in g; use the same basis as the other measurements. |
Understanding your result
The result is a scientific reference calculation under the model assumptions on this page. It does not assess hazards, chemical compatibility, purity, solubility, equipment limits or clinical meaning.
Common mistakes
- Using solvent volume in place of final solution volume, or mass concentration in place of molar concentration.
- Ignoring units, reaction coefficients, activity assumptions or the stated temperature/model limits.
Check your calculation
- Check the units and balance/coefficients against the worked example. For real laboratory work, verify SDS information and the applicable procedure independently.

- What percentage of theoretical product was obtained
How it works
Divide actual product amount by the positive theoretical amount, then multiply by 100. Use the same units and purity basis; a value above 100% calls for reviewing the measurement and assumptions.
Worked example
Enter Actual product mass: 8 g; Theoretical product mass: 10 g. Results: Percent yield: 80 %.
