1. We write down the equation of carbon combustion:

C + O2 = CO2;

2. calculate the chemical amount of carbon:

n (C) = m (C): M (C) = 18: 12 = 1.5 mol;

3. Determine the amount and calculate the volume of oxygen required for complete combustion of carbon:

n (O2) = n (C) = 1.5 mol;

V (O2) = n (O2) * Vm = 1.5 * 22.4 = 33.6 liters.

Answer: 33.6 liters.
