Equation of State
Ideal Gas Law
The gas-phase density is calculated using the ideal gas law, which describes the relationship between pressure, temperature, and molar concentration:
| Symbol | Description | Unit |
|---|---|---|
| Gas molar concentration | mol m⁻³ | |
| Temperature | K | |
| Pressure | Pa | |
| Ideal gas constant | J mol⁻¹ K⁻¹ |
