A sealed balloon is filled with 1.20 L of helium at 23°C and 1.00 atm. The balloon rises to a point in the atmosphere where the pressure is 250. torr and the temperature is -27°C. What is the change in volume of the balloon as it ascends from 1.00 atm to a pressure of 250. torr?

  • Chemistry -

    (P1V1/T1) = (P2V2/T2)
    You must change atm to torr or torr to atm. Remember T must be in kelvin.
