**Gas Law problem.... please help**

**Calculate the average kinetic energies of the CH4 and N2 molecules at 294 K and 574 K.**

I've tried every possible way I could think of. I can't get the right answer. I don't know what equation to use anymore, I've done it all and nothing works.

I got all these answers:

676

4.06e-21

4333.34

*J/molecule*3 sig figs

And none of them are good. I'm getting annoyied, someone give me a hint please. Thanks
