    V = 12.93 L

    Explanation:

    Given dа ta:

    Number of moles = 0.785 mol

    Pressure of balloon = 1.5 atm

    Temperature = 301 K

    Volume of balloon = ?

    Solution:

    The given problem will be solve by using general gas equation,

    PV = nRT

    P = Pressure

    V = volume

    n = number of moles

    R = general gas constant = 0.0821 atm. L / mol. K

    T = temperature in kelvin

    Now we will put the values.

    V = nRT/P

    V = 0.785 mol * 0.0821 atm. L / mol. K * 301 K / 1.5 atm

    V = 19.4 L / 1.5

    V = 12.93 L
