The Ideal Gas Law

#### Q. Helium-filled balloons are used to carry scientific instruments high into the atmosphere. Suppose a balloon is launched when the temperature is 22.0°C, and the barometric pressure is 755 mm Hg. If the balloon's volume is 4.59 x 10^4 L (and no helium escapes from the balloon), what will the volume be at a height of 20 miles, where the pressure is 76.0 mm Hg, and the temperature is -33.0°C?
