Formula and methodology
Formula: Density=pressure×molar mass/(R×absolute temperature), R=8.314462618 J/(mol·K).
The ideal-gas relation expresses density as pressure and molar mass divided by thermal scale.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Absolute pressure — Pa; minimum 1.0E-6; maximum 1.0E+15
- Molar mass — kg/mol; minimum 1.0E-6; maximum 10000
- Absolute temperature — K; minimum 1.0E-6; maximum 1000000
Worked example
| Input | Value |
|---|---|
| Absolute pressure | 101325 |
| Molar mass | 0.02897 |
| Absolute temperature | 288.15 |
Ideal-gas density ≈1.225 kg/m³.
Assumptions and limits
- Pressure and temperature are absolute and SI-compatible.
- The gas follows the ideal model at the entered state.
- Real-gas effects, humidity, mixtures, and phase changes are not modeled.
