How much carbon dioxide is generated when 1 liter of propane is burned?

The propane combustion reaction is described by the following equation:

C3H8 + 5O2 = 3CO2 + 4H2O;

When one mole of propane is burned, three moles of carbon dioxide are formed.

Let’s find the molar amount of the substance contained in 1 liter of propane.

One mole of ideal gas takes up a volume of 22.4 liters.

Accordingly, 1 liter of propane contains 1 / 22.4 = 0.0446 mol of the substance.

When this amount of propane is burned, 0.0446 x 3 = 0.13338 mol of carbon dioxide is formed.

This amount of carbon dioxide takes up a volume of 0.1338 x 22.4 = 3 liters.
