1. Let’s compose the equation of the chemical reaction:

C + O2 = CO2.

2. Find the chemical amount of burned coal:

n (C) = m (C) / M (C) = 96 g / 12 g / mol = 8 mol.

3. According to the reaction equation, we find the chemical amount of released carbon dioxide, and then its volume (Vm – molar volume, constant equal to 22.4 l / mol):

n (CO2) = n (C) = 8 mol.

V (CO2) = n (CO2) * Vm = 8 mol * 22.4 L / mol = 179.2 L.

Answer: V (CO2) = 179.2 liters.
