**DrBob222**, Friday, April 8, 2011 at 1:19am7.2 gO2/32 g/mol = 0.225 moles O2.

I would use PV = nRT and solve for P, then add 4/4 = 1.0 mole He to make a total of 1.225 mol combined gases and plug into PV = nRT again and solve for V.

You also can use a ratio/proportion.

(33/0.225) = (V/1.225) and solve for V.
