Calculate the volume of carbon dioxide that is formed when 250 g of limestone containing

Calculate the volume of carbon dioxide that is formed when 250 g of limestone containing 20% impurities is dissolved in acetic acid.

When 1 mol of limestone is dissolved in acetic acid, 1 mol of gaseous carbon dioxide is synthesized.

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

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

N CaCO3 = 250 x 0.8 / 100 = 2 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 substance and the standard volume of 1 mole of gaseous substance.

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

V CO2 = 2 x 22.4 = 44.8 liters;
