You have a 25.0 L cylinder of helium at a pressure of 132 atm and a temperature of 19 ∞C. The He is used to fill balloons to a volume of 2.50 L at 732 mm Hg and 27 ∞C. How many balloons can be filled with He? Assume that the cylinder can provide He until its internal pressure reaches 1.00 atm (i. e., there are 131 atmospheres of usable He in the cylinder).
