Formula for Calculating CO2 Density
The density of a gas like CO2 is calculated using the basic formula:
Density = Mass / Volume
Where:
- Mass is the mass of the CO2 (in kilograms, kg).
- Volume is the volume of the CO2 (in cubic meters, m³).
For example, if the mass of CO2 is 5 kg and the volume is 2 m³, the density would be calculated as:
Density = 5 kg / 2 m³ = 2.50 kg/m³
Example Calculation
Let’s go through an example to better understand how this works.
Example 1:
- Mass of CO2: 10 kg
- Volume of CO2: 4 m³
Step-by-Step Calculation:
- Formula:
Density = Mass / Volume - Insert Values:
Density = 10 kg / 4 m³ - Perform Calculation:
Density = 2.50 kg/m³
So, the density of CO2 in this case is 2.50 kg/m³.
