What Is Gas Density?
Gas density is the mass of a gas per unit volume. It varies depending on pressure, molar mass and temperature.
How is it calculated?
How Is It Calculated?
d = (P × M) ÷ (R × T)
M: molar mass, R: 8,314, T: Kelvin.
- Enter the pressure, molar mass and temperature.
Frequently Asked Questions
What happens to density when temperature increases?
At constant pressure, if the temperature rises the gas expands and its density decreases.
