**DrBob222**, Wednesday, October 8, 2008 at 11:41pmUse PV = nRT for the 5.50 L tank of oxygen. Calculate n = # mols O2 in the tank. There is no T listed so pick any T and use it throughout the problem. I would pick 27 C because that's 300 K and that is very close to room T. (Don't forget to use Kelvin for T in PV = nRT).

Using n mols oxygen, and the equation you wrote earlier, calculate mols acetylene needed to exactly react with the oxygen in the 5.50 L tank. Then use PV = nRT again and solve for P of the acetylene in the 3.5 L tank.
