I wonder to start with how one weighs that and how much it is in volume. For example 1 kg CO2 is that the amount of a bucket or a measuring cup of 1 liter. Actually the specific gravity of the CO2. I once made the calculation when we drive from Leuven to Kortrijk in I came to around 32 Kg!
Answer
Like all substances, CO . has2 a mass, which is expressed in grams. It is important to note that gram is a measure of mass, not weight (the Newton is used to express weight in a scientific way). For example, you will be weightless in space (0 Newton), but you will still have the same mass (50, 60, xx kg).
To calculate the approximate volume occupied by 1 kg of CO2, you can use the ideal gas law. The volume then depends on the air pressure, the temperature, and the amount of gas. The amount is expressed in mol. The molar mass of CO2 is about 44 g/mol, so every 44 g CO2 is 1 mole. In 1 kg CO2 is then rounded to 22.72 mol CO2.
Given that pressure is 1013 hPa (‘average air pressure’) and temperature is 0ËšC, each mole of gas takes up about 22.4 liters of space. At a temperature of 25ËšC, the gas is warmer and expands, taking up 24.45 liters. 1 kg CO2 takes 509 to 556 liters, a little more than half a cubic meter.
This times 32 provides an estimated amount of 17 cubic meters of CO . produced2 gas.
