Density of Ideal Gas Calculator
What is the Density of an Ideal Gas?
The density of an ideal gas is a measure of how much mass is present in a given volume at a specific temperature and pressure. According to the ideal gas law, the density of an ideal gas can be determined using the formula \( \rho = \frac{PM}{RT} \), where:- P is the pressure of the gas (in pascals, Pa)
- M is the molar mass of the gas (in kg/mol)
- R is the universal gas constant (8.314 J/(mol·K))
- T is the temperature in Kelvin (K)
How to Calculate the Density of an Ideal Gas
To calculate the density of an ideal gas, use the formula:- Density (ρ) = (Pressure × Molar Mass) / (Gas Constant × Temperature)
| Gas | Pressure (Pa) | Molar Mass (kg/mol) | Temperature (K) | Density (kg/m³) |
|---|---|---|---|---|
| Air | 101325 | 0.02897 | 298 | 1.146 |
| Oxygen | 101325 | 0.03200 | 298 | 1.243 |
| Nitrogen | 101325 | 0.02802 | 298 | 1.130 |
| Carbon Dioxide | 101325 | 0.04401 | 298 | 1.823 |
