Took a pic of the paper I tried it on it on, has the exact problem description written at top, and what I tried. Figured that would be easier then typing all that. The answer is supposed to be 2.0.

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.

  • $\begingroup$ I don't really get what you are asking. Do you want us to check your calculation? It might be easier for you to just take a picture and post it here, but it is much harder for everybody else. Also this way, this is not helping anyone how looks for a solution of a similar problem. Please consider the users helping out here are doing this in their free time (just for fun and giggles). $\endgroup$ – Martin - マーチン Feb 27 '15 at 9:58

You used the wrong version of $R$. Try using $R = 8.314 J mol^{-1} \ K^{-1}$.
