A 14.5L 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.

Use PV = nRT to calculate the number of moles, n, in the 14.5L tank. (Pressure = 200 atm  1 atm since 1 atm is the minimum). Then use PV = nRT to determine the moles to fill one (1) balloon. Set up a proportion to determine how many balloons can be filled.
