Asked by Aaqib Zaman

A cylinder containing 15.0 L of helium gas at a pressure of 165 atm is to be used to fill party balloons. Each balloon must be filled to a volume of 2.0 L at a pressure of 1.1 atm. What is the maximum number of balloons that can be inflated? Assume that the gas in the cylinder is at the same temperature as the inflated balloons. (HINT: The "empty" cylinder will still contain helium at 1.1 atm.)

Use PV = nRT and calcualate mols in the cylinder.
Use PV = nRT and calculate mols left when the cylinder is "empty".
Subtract to see mols He available to fill balloons.
Use PV = nRT and calculate mols needed to fill one balloon.

mols He/1 balloon x # balloons = total mols He available.

Can't use PV=nRT to solve for n (moles). Temperature is not given.
