Mole Fraction Calculator
Find the mole fraction of one component in a mixture.
Open toolFind ideal-mixture partial pressure as mole fraction × total pressure. Provide Gas mole fraction, Total absolute gas pressure (Pa) to compute results directly in your browser. Dalton ideal-gas mixture model. Use absolute total pressure, not gauge pressure. Inputs and results use floating-point numbers; output shows up to 12 significant digits. Rounding can occur.
Enter the inputs, then select Calculate.

Review the input parameters, allowed value ranges, and worked reference cases for the Partial Pressure Calculator below before running your calculation.
| Parameter / Scenario | Default / Sample Value | Rule or Allowed Range | Output / Usage Note |
|---|---|---|---|
| Input: Gas mole fraction | 0.2 | Range: 0 to 1 | Required workspace parameter |
| Input: Total absolute gas pressure (Pa) | 100000 | Range: 0 to 1000000000.0 | Required workspace parameter |
| Worked Case 1: Baseline run (Gas mole fraction = 0.2) | Preloaded / test values | Find ideal-mixture partial pressure as mole fraction × total pressure | Gas mole fraction: 0.2; Total absolute gas pressure (Pa): 100000. The displayed output is 20000 Pa. |
| Worked Case 2: Comparison scenario (Comparison gas mole fraction check) | Preloaded / test values | Find ideal-mixture partial pressure as mole fraction × total pressure | Gas mole fraction: 0; Total absolute gas pressure (Pa): 100000. The displayed output is 0 Pa. |
