Energy content of gasoline and hydrogen comparative math question

[SteamKing]

Yes. So you have, for burning gasoline:

• 12 atomic masses C corresponds to 44 atomic masses CO2
• 70g CO2 corresponds to 1MJ energy
• 1 gallon gasoline corresponds to 36,315 g C

So how many J energy correspond to 1 gallon gasoline?

This is incorrect. According to the attachment in Post #4, 1 gallon of gasoline has a carbon content of 2421 g, not 36,315 g. The latter figure is for 15 gallons of gasoline.

Well spotted - thanks. But fortunately courtneywetts used the right ratio later.
