I know that when burned, methane produces a theoretical yield of 891 kilojoules per mole. My question is that if America burned all the methane it produced in a year, how many joules of heat energy would have been released? I'm using 22.4 L per mole. I don't understand how I'm supposed to solve this without more information....am I missing something? Thanks for any help you may be able to give me.


Wow, I feel insanely stupid. I completely missed the first part of the question. It told me that it's 24.37 trillion cubic feet. I converted it to 6.900 x 10^11 meters cubed. I'm ridiculous.
