Determine the amount of oxygen required to interact with carbon if the reaction produces 20 liters of carbon dioxide (I).

The carbon oxidation reaction is described by the following chemical reaction equation:

C + O2 = CO2;

Carbon reacts with oxygen in equal molar amounts.

The same amount of carbon dioxide will be synthesized.

Let’s calculate the chemical amount of carbon dioxide.

To do this, we divide its volume by the volume of 1 mole of gas.

N CO2 = 20 / 22.4 = 0.893 mol;

The same amount of oxygen will be required.

Let’s find its volume.

To do this, multiply the amount of substance by the volume of 1 mole of gas (22.4 liters).

V О2 = 0.893 x 22.4 = 20 liters
