Hey, my textbook is not helping at all. Here's the problem followed by what I've done on it so far.
A sample of an ideal gas is taken through the cyclic process abca shown in Fig. 20-20; at point a, T = 241 K.
graph:

There are two parts of the question I could not answer. One is how many moles are in the sample? I plugged the values given into pV = nRT, and I got n = .001248. That answer is incorrect.
Secondly, what is the net heat added to the gas during this cycle? I don't know where to begin for this. The textbook is usually very clear, but for some reason doesn't include anything on this.
If anyone could help me get on the right track, I would greatly appreciate it.
