2.) You have just volunteered to decorate the gym for the winter dance with 300.0
Helium balloons. Their is a store in town that will rent a 25 L. helium tank with a
pressure of 30.0 atm. Each balloon, when filled, holds 2.5 L of helium gas at a pressure of
1.04 atm. Will one tank be enough to fill all 300.0 balloons? Assume that the gas
temperature does not change as the balloons are filled. If not, how many balloons can be
filled with the tank of gas?
