What to enter
| Input | Meaning and units |
|---|---|
| Reactant amount (mol) | Enter reactant amount in mol; use the same basis as the other measurements. |
| Reactant coefficient (1) | Enter reactant coefficient in 1; use the same basis as the other measurements. |
| Product coefficient (1) | Enter product coefficient in 1; 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.

Common uses
- What product amount corresponds to a known reactant amount
How it works
Scale the known reactant amount by the ratio of positive coefficients in a balanced reaction. The result is a theoretical product amount, not a predicted experimental yield.
Worked example
Enter Reactant amount: 2 mol; Reactant coefficient: 2 1; Product coefficient: 3 1. Results: Product amount: 3 mol.
