| The reaction equation for the thermal decomposition of calcium carbonate:
CaCO3 (t) = CaO + CO2
Amount of calcium carbonate substance:
v (CaCO3) = m (CaCO3) / M (CaCO3) = 50/100 = 0.5 (mol).
According to the reaction equation, from 1 mol of CaCO3, 1 mol of CO2 is formed, therefore:
v (CO2) = v (CaCO3) = 0.5 (mol).
Thus, the volume of carbon dioxide measured under normal conditions (n.o.):
V (CO2) = v (CO2) * Vm = 0.5 * 22.4 = 11.2 (l).
Answer: 11.2 (l).
