Calculation Process
Follow these steps to calculate the density of a gas:
- Determine the pressure (( P )) of the gas.
- Identify the molar mass (( M )) for the specific gas.
- Use the universal gas constant (( R )) in appropriate units.
- Measure or convert the temperature (( T )) to Kelvin.
- Substitute the values into the gas density formula and compute for ( rho ).
Example Calculation
Let’s calculate the density of oxygen gas (( O_2 )) at a pressure of 1 atm and a temperature of 298 K.
