Octane [C8H18] is one of the main ingredients in gasoline and combusted by the oxygen in the air in your car’s engine in the reaction below. FYI - D gasoline = 0.75 g/mL.

2 C8H18(l) + 25 O2(l) → 18 H2O (l) + 16 CO2(g)

b. On a road trip you burn enough octane to create 1.50 x 105g of water. How many grams of oxygen was needed to combust with the octane?
