I am stuck on this question. I took a screen shot of the question, please provied the forumula you used as well. Thanks

A gas is allowed to expand at constant pressure until it reaches its final volume. It is then cooled at constant volume until it reaches its final pressure. The initial state of 1.00 mol of a dilute gas is P1 = 3.18 atm, V1 = 0.95 L, and Eint 1 = 414 J, and its final state is P2 = 2.00 atm, V2 = 3.12 L, and Eint 2 = 982 J. Illustrate this process on a PV diagram. (Do this on paper. Your instructor may ask you to turn in this work.) Calculate the work done by the gas. J Find the heat absorbed by the gas during this process. J

Explanation / Answer

A) w= PdV

= 3.18*(3.12-0.95)*101.324 J

= 699.196 J

b)Q = dU+W

= 982-414+699.196

= 1267.196 J
