Strategy:
 Combustion of long-chain hydrocarbons requires stoichiometric balance. First calculate the mass of 1 litre of fuel using its density, find the moles, and then use the balanced equation to find the oxygen required and carbon dioxide released by mass.

Step 1: Balance the combustion equation

Step 2: Calculate moles of fuel in 1 Litre
Density , so 1 L weight .
Molar mass of .

Step 3: Calculate mass of reactants and products
- Oxygen: Moles . Mass .
- Carbon Dioxide: Moles . Mass .
