How much oxygen is required for the complete combustion of 2 g of carbon?

The oxidation reaction of carbon 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 a substance contained in 2 grams of carbon.

To do this, divide the weight of the substance by the weight of 1 mole of the substance.

M C = 12 grams / mol;

N C = 2/12 = 0.167 mol;

To oxidize such an amount of a substance, 0.167 mol of oxygen is needed.

Let’s calculate its volume.

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

V O2 = 0.167 x 22.4 = 3.741 liters;
