Question

A 14.5-L tank is filled with H2 to a pressure of 2.00 102 atm. How many balloons (each 2.00 L) can be inflated to a pressure of 1.00 atm from the tank? Assume that there is no temperature change and that the tank cannot be emptied below 1.00 atm pressure.
I would use PV = nRT and determine the number of moles (n) in the tank. Use it again to determine the number of moles for each balloon at 2. L apiece. Go from there.
