**DrBob222**, Monday, December 5, 2011 at 8:06pmI would use PV = nRT and solve for n = numbr of moles of the gas at the third stage (you know P, V, R, and T)

Then double that amount to find moles at stage and solve for P2. Then I believe you can use (P1V1/T1) = (P2V2./T2) and solve for P at the first stage.
