so then: 1*2.3*315.15/Pf*4.5*308.15 Pf=2.38315.15/4.5*308.15 724.85/1386.68 Pf=0.52 ok, great! Thank you very much. I was adding an extra step by subtracting 2.3 from 4.5 and I have no idea why I did that.

Physics
In an expansion of this type, P*V^g = constant where g is the specific heat ratio Cp/Cv, which for a monatomic gas is 5/3. Let Pf be the final pressure. The final volume is Vf = 3 Vo. Thus Po*Vo^5/3 = Pf*(3Vo)^5/3 Pf/Po = (1/3)^(5/3) = 0.160

(a) If the gas expands isothermally, that means T is constant, so Tf = Ti (b) When T = constant, p*V = constant Therefore pi*Vi = pf*Vf = 6 pf*Vi pf = pi/6
