You 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.
I 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.
