If each gasoline molecule releases 57 ev of energy upon

A motorcycle engine does work at a rate of about 6 kW while burning a liter of gasoline every 20 minutes.

(a) Given that the mass of one gasoline molecule is about 114 atomic mass units (1 amu = 1.66 × 10^-27 kg), and the mass of a liter of gasoline is 0.7 kg, how many gasoline molecules are there in a liter?

(b) If each gasoline molecule releases 57 eV of energy upon oxidation, how much heat energy (in joules) is provided by burning one liter of gasoline?

(d) What is the efficiency of this motorcycle engine?
