From the given balanced chemical reaction,
C + O2 -> CO2
the mass ratio of the carbon and oxygen that is needed for the reaction is 12:32. Simplifying the ratio gives 3 unit mass C is to 8 unit mass O2. Given 18 g of carbon,
18 g x (32 g oxygen / 12 g carbon) = 48 grams.
For the given product, the ratio of oxygen to carbon dioxide is 32: 44.
72 g CO2 x (32 g O2 / 44 g CO2) = 52.36 grams
