Can you help with "c" was told to use as less digits as possible  3. An unknown number of moles of an ideal monoatomic gas expand reversibly from Vi = 3.10 m3 to Vf = 4.00 m3, at a constant pressure of 1.47 atm and an initial temperature of 300 K. a. Find the number of moles of gas.         185b. Find the final temperature of the gas K.         387 c. Calculate the work done by the gas.      134053 J <<<< this is the wrong answer.       (should use less digits for this answer)

A thermodynamic process can be represented using a PV diagram where the pressure and volume at every stage is recorded. In the thermodynamic process shown below the work done by the system is РА A O the area under the PV curve and positive the area under the PV curve and negative B is the product of the change in volume during the process and the change in pressure. cannot be found from the PV graph
