Homework Statement
At a constant temperature, 0.85 mol of an ideal gas changes its pressure from 350 Torr to 125 Torr. Calculate the entropy change for this expansion process.
Homework Equations
Ideal gas: PV=nRT
ΔS = nRln(Vf/Vi)
The Attempt at a Solution
I'm stuck on how to find the volume given the change in pressure, and it being an isothermal process. What am I missing?
