what is the total pressure in the vessel?

**DrBob222**, Sunday, April 10, 2011 at 9:29pmThere may be an easier way to work this problem but I would do the following:

Use PV = nRT and solve for n for oxygen.

Use PV = nRT and solve for n for nitrogen.

noxygen + nnitrogen = total n.

Then PV = nRT, substitute the new volume and solve for total P. There is no T listed in the problem but you can use any T you wish as long as the same T is used throughout.
