1. The problem statement, all variables and given/known data Estimate the amount of energy (in J) in a gallon of gasoline by imagining that there is about 4 eV of energy for every carbon atom. 3. The attempt at a solution I don't know of any equations that would relate eV to J. But I do know that there are 6.022 x 10^23 atoms/mole. How do I get started on this?
