1. The problem statement, all variables and given/known data

Calculate the work done by the gas during process 1-> 3-> 6.
Express your answer in terms of Po and Vo.


2. Relevant equations

W=integral(pv) from V1-V2
W=PVln(V2/V1)

3. The attempt at a solution

3Po*V*ln(3Vo/Vo)

I'm not sure what I'm doing wrong, it keeps telling me I'm off by a multiplicative factor.. Should I be using W=nRT ln(V2/V1) ?
