To calculate the work for Path A, you use the formula for work of an isothermal, reversible expansion: w=nRTln(v2/v1). To solve for moles of gas, you can use PV=nRT since it is an ideal gas. Once you know the moles of gas, you can plug it into the formula along with the other given information to so...
