Assume that the balloon is filled with carbon dioxide gas at 20°C and standard pressure. Use the ideal gas law to calculate the number of moles and mass of CO2 in each balloon at maximum inflation. balloon 1 volume-150.53 balloon 2 volume- 248.47
balloon 3 volume- 463.23

  1. I don't get it. Just use PV = nRT and solve for n. Balloon 1.
    P = 1 atm
    V = 150.53
    n - ?
    R = 0.08205
    T = 273 + 20 = 293 K
    Solve for n = number of mols.
    Then grams = n x molar mass = ?
