One of the alkanes in gasoline is octane, C8H18, which has a density of 0.803 g/cm3 and Δ H = −510 kJ/mol. Suppose a hybrid car has a fuel tank with a capacity of 11.9 gal and has a gas mileage of 45 mi/gal. (1.10, 6.7, 8.3, 8.5, 9.5)

Octane is one of the components of motor fuel.

a. Draw the condensed structural formula for octane.

---

b. Write a balanced chemical equation for the complete combustion of octane including the heat of reaction.

---

c. What is the energy, in kilojoules, produced from one tank of fuel assuming it is all octane?

---

d. How many molecules of C8H18 are present in one tank of fuel assuming it is all octane?

---

e. If this hybrid car is driven 24 500 miles in one year, how many kilograms of carbon dioxide will be produced from the combustion of the fuel assuming it is all octane?
