What is the volume of carbon monoxide (4) produced by the combustion of 1 kg of coal with a carbon content of 95%?

The reaction of carbon with oxygen occurs in accordance with the following chemical reaction equation:

C + O2 = CO2;

For oxidation of 1 mole of carbon, 1 mole of oxygen is required. This releases 1 mole of carbon dioxide.

Let’s find the amount of carbon.

The weight of pure carbon is 1000 x 0.95 = 950 grams;

M C = 12 grams / mol;

N C = 950/12 = 79.17 mol;

When this amount of carbon is burned, 79.17 moles of carbon dioxide are released.

Let’s calculate its volume.

One mole of gas under normal conditions fills a volume of 22.4 liters.

The volume of carbon dioxide will be equal to:

V CO2 = 79.17 x 22.4 = 1773.4 liters = 1.77 m3;
