I have a problem in which I'm solving for -w. My equation is this:
-w= nRT ln V2/V1
However, I don't know the value of n, but I do know the values of P, V, and T. If I fill in (PV/RT) for n in the above equation, would I be using the energy R or the gas R?

The R you use is the Gas Constant.
If V is in liters, P is in atm and T is in K, the value of R is
R = 8.205*10^-2 liter-atm/(mole-K)

thank you drwls
