Answer :
Final answer:
The approximate energy content of gasoline is closest to option B, 37.9 kWh/gallon, based on conversion from 130 MJ of chemical energy per gallon.
Explanation:
The approximate energy content of gasoline in kWh per gallon can be calculated by understanding that a gallon of gasoline contains about 130 MJ (megajoules) of chemical energy, and knowing the conversion factors between megajoules and kilowatt-hours. Since 1 MJ equals 0.27777778 kWh, we can perform the following calculation: 130 MJ/gallon * 0.27777778 kWh/MJ = 36.11 kWh/gallon. Therefore, the correct answer to the question is B. 37.9 kWh/gallon, as it is the closest approximation to the computed value.
