Gas Law Problem

  1. Nov 29, 2007 #1
    [SOLVED] Gas Law Problem

    1. The problem statement, all variables and given/known data
    An expandable balloon contains 1400L of He at 0.950 atm pressure and 18 deg C. At an altitude of 22 miles (temp 2 deg C, and pressure 4 Torr. What will be the volume of the balloon?


    2. Relevant equations
    (P1V1)/T1 = (P2V2)/T2
    1 atm = 760 Torr
    K = 273 + Deg C

    3. The attempt at a solution
    First thing I did was to convert Torr to atm, so 4 Torr = .005 atm.
    I then solved for V2 so I get the equation :
    V2 = (T2P1V1)/(T2P2) or (275k(0.95atm)1400L)/(291k(.005atm))= 25,1374 L

    My Answer seems way off as it is so huge. Where did I make a mistake?
    Thanks

    your calculations are correct, its the low pressure that is making it so big

    Thanks. It just looked off to me, glad you clarified for me. That would have to be one stretchy balloon though :)
