How much oxygen is required to produce 40 liters of CO2 gas?

C + O2 = CO2

According to the stoichiometry of the chemical reaction, the amount of the substance of the resulting carbon dioxide is equal to the amount of the substance of the consumed oxygen. Consequently, the volumes of these gases will also be equal.

V (O2) = V (CO2) = 40 l.

Answer: V (O2) = 40 liters.
