What to enter
| Input | Meaning and units |
|---|---|
| Mole fraction (1) | Enter mole fraction in 1; use the same basis as the other measurements. |
| Total pressure (Pa) | Enter total pressure in Pa; 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.

How it works
Multiply total pressure by the stated mole fraction for an ideal gas mixture. This is pressure arithmetic, not container sizing or a pressure-limit assessment.
Worked example
Enter Mole fraction: 0.25 1; Total pressure: 100000 Pa. Results: Partial pressure: 25000 Pa.
