How many grams of air are required for an automobile to travel from Thunder Bay,Ontario, to Smooth Rock Falls, Ontario? This is
a distance of 670 km. Assume the following:
•Gasoline is pure octane, C8H18. (Gasoline is actually a mixture of hydrocarbons.)
• The average fuel consumption is 10 L per 100 km.
• Air has a density of 1.21 g/L.
• The density of the gasoline is 0.703 g/mL.
• The balanced chemical equation for the complete combustion of octane is 2C8H18(e) + 25O2(g) → 16CO2(g) + 18H₂O(g)
