108 kg of calcium carbonate were calcined with silicon oxide. determine the amount of the substance and the mass of the formed calcium silicate.

The reaction of obtaining calcium silicate by fusing soda with sand is described by the following equation:

CaCO3 + SiO2 = CaSiO3 + CO2;

Find the chemical amount of calcium carbonate:

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

М СaСO3 = 40 + 12 + 16 x 3 = 100 grams / mol;

n СaСO3 = 108,000 / 100 = 108 mol;

From this amount of calcium carbonate, an equivalent amount of calcium silicate of 108 mol can be obtained.

Let’s calculate its mass.

М СaSiO3 = 40 + 28 + 16 x 3 = 116 grams / mol;

m СaSiO3 = 108 х 116 = 12 528 grams = 12.528 kg;
