Pure liquid octane (d = 0.702 g/mL) is used as the fuel in a test of a new automobile drive train. How much energy (in kJ) is released by complete combustion of of all the octane in a 20.4 gal fuel tank?
The energy delivered to the drive wheels at 75 mph is 60500 kJ/h. Assuming all the energy is transferred to the wheels, what is the cruising range (in km) of the car on a full tank of gas?
Please help me out
