Easily calculate the density of any gas using our online Gas Density Calculator. Input pressure, temperature, and molar mass to get precise results based on the Ideal Gas Law. Essential for chemistry, physics, and engineering students and professionals.
Formula:
The Gas Density (ρ) is calculated using a rearranged form of the Ideal Gas Law:
ρ = (P × M) / (R × T)
- ρ is the Gas Density (e.g., in g/L or kg/m³)
- P is the Absolute Pressure of the gas (e.g., in atm, Pa)
- M is the Molar Mass of the gas (e.g., in g/mol or kg/mol)
- R is the Ideal Gas Constant (0.08206 L·atm/(mol·K) for internal calculations in this tool)
- T is the Absolute Temperature of the gas (in Kelvin)
