Determine the volume of carbon dioxide that is formed from sodium carbonate 25g.

1. Let’s write down the reaction of obtaining carbon dioxide from sodium carbonate by interaction with sulfuric acid:

Na2CO3 + H2SO4 = Na2SO4 + H2O + CO2 ↑;

2.Calculate the chemical amount of carbonate:

n (Na2CO3) = m (Na2CO3): M (Na2CO3);

M (Na2CO3) = 23 * 2 + 12 + 3 * 16 = 106 g / mol;

n (Na2CO3) = 25: 106 = 0.2358 mol;

3. Determine the chemical amount and volume of the emitted gas:

n (CO2) = n (Na2CO3) = 0.2358 mol;

V (CO2) = n (CO2) * Vm = 0.2358 * 22.4 = 5.28 dm3.

Answer: 5.28 dm3.
