What is the volume of carbon dioxide circulation during the complete combustion of 4 g of methane.

The methane oxidation reaction is described by the following chemical reaction equation.

CH4 + 2O2 = CO2 + 2H2O;

According to the coefficients of this equation, 2 oxygen molecules are required to oxidize 1 methane molecule. This synthesizes 1 molecule of carbon dioxide.

The molar volume of the gas is standard and under normal conditions it fills a volume of 22.4 liters.

The amount of methane is:

M CH4 = 12 + 4 = 16 grams / mol;

N CH4 = 4/16 = 0.25 mol;

Since the molar volume of the gas is standard and the amounts of methane and carbon dioxide are equal, the volumes of carbon dioxide and methane will be equal:

The volume of carbon dioxide will be 22.4 x 0.25 = 5.6 liters.
