What volume of carbon dioxide is formed when interacting with an excess of nitric acid 250 g of limestone?

The reaction of interaction of limestone with nitric acid is described by the following chemical reaction equation:

CaCO3 + 2HNO3 = Ca (NO3) 2 + H2O + CO2;

The decomposition of 1 mol of limestone synthesizes 1 mol of gaseous carbon dioxide.

Let’s calculate the available chemical amount of calcium carbonate substance.

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

N CaCO3 = 250/100 = 2.5 mol;

During the reaction, the same amount of carbon dioxide will be synthesized.

Let’s calculate its volume.

To do this, multiply the amount of the substance and the standard volume of 1 mole of the gaseous substance.

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

V CO2 = 2.5 x 22.4 = 56 liters;
