| 1. We calculate the chemical amount of carbon:
n (C) = m (C): Mr (C) = 3: 12 = 0.25 mol;
2.the chemical amount of the obtained carbon dioxide and the initial carbon are equivalent:
n (CO2) = n (C) = 0.25 mol;
3.determine the volume of carbon dioxide:
V (CO2) = n (CO2) * Vm = 0.25 * 22.4 = 5.6 liters.
Answer: 5.6 liters.
