How Many Moles Of C3H8 Reactant Will Be Needed To Produce The Specified Number Of Moles Of CO2 Product 14 Moles CO2?

When an organic compound is burned in the presence of oxygen, carbon dioxide and water are produced. The general chemical reaction is;

Organic compounds + oxygen ------ > carbon dioxide + water

When propane is burned in the presence of oxygen, carbon dioxide and water are formed.

C3H8+ 5O2 ------> 3CO2 + 4H2O

If there are 14 moles of carbon dioxide in products then, moles of propane used in reactants are;

14/3 C3H8+ 5*14/3O2 ------> 3*14/3CO2 + 4*14/3H2O

14/3C3H8+ 70/3 O2 ------> 14 CO2 + 56/3H2O

14/3 moles of propane are used to produce 14 moles of carbon dioxide.
