**Dr Russ**, Friday, November 21, 2008 at 10:38amYou will need to assume that it is an ideal gas and that 1 mole of any ideal gas occupies 22.4 litres at STP (273 K, 1 atm).

then use P1V1/T1=P2V2/T2

I would convert 120 L to STP and then compare the volume obtained with 22.4 litres as this then gives you the number of moles.

**Jeremy**, Sunday, November 23, 2008 at 12:36pmI disagree with Dr. Russ's method. Use PV=nRT, where P=2.3atm, V=120L, n= unknown moles, R= .08205, T=340K.

Solve for n to get 9.9 mol gas.

Without significant figures, n=9.893536939.
