A weather balloon is filled with helium that occupies a volume of

4.39 x 10^4 L at 0.995 atm and 32.0°C. After it is released, it rises to a location where the pressure is 0.720 atm and the temperature is -14.1°C. What is the volume of the balloon at that new location?

(P1V1/T1) = (P2V2/T2)
Remember T must be in kelvin.
