What volume of carbon dioxide and what mass of sodium oxide will be obtained

What volume of carbon dioxide and what mass of sodium oxide will be obtained by decomposition of sodium carbonate, weighing 400 kg, containing 10 percent of impurities

The thermal decomposition reaction of calcium carbonate upon heating is described by the following chemical reaction equation:

CaCO3 = CaO + CO2 ↑;

Let’s calculate the chemical amount of calcium carbonate. To do this, we divide its weight by the mass of 1 mole of the substance.

M CaCO3 = 40 + 12 + 16 x 3 = 100 grams / mol;

N CaCO3 = 400,000 x 0.9 / 100 = 3600 mol;

The same molar amount of carbon dioxide could theoretically be synthesized.

To calculate its volume, you need to multiply the amount of substance by the volume of 1 mole of gas (filling volume 22.4 liters).

V CO2 = 3600 x 22.4 = 80 640 liters = 80.64 m3
