How much oxygen is required to oxidize 18 g of carbon?

We form the reaction equation: C + O2 = CO2.
1) According to the periodic table, we determine the molar mass of carbon: 12.
2) Find the amount of carbon substance. To do this, divide the mass of carbon by its molar mass: 18/12 = 1.5 mol.
3) According to the reaction equation, there is one mole of oxygen for one mole of carbon. This means that the amount of oxygen is 1.5 mol.
4) Find the volume of oxygen. To do this, multiply the amount of substance by the molar volume: 1.5 * 22.4 = 33.6 liters – the answer.
