For a) I just plugged in e to the equation and got the answer. I am stuck on the rest.
So for b) I plugged in the CO2 they gave us into the e equation and then calculated e and plugged it into the Ts equation, but I keep getting an error on my calculator because I keep getting a negative number in the (2/2-e)^1/4 part and that shows an error in my calculator (my e is really huge).
I don't know what to do!
Your epsilon should be less than $1$. If you multiply $410 \times 0.0001$ what do you get?
