    168.4 mL

    Explanation:

    Data Given

    initial volume V1 of gas in balloon = 100 mL

    initial pressure P1 of gas in balloon = 3.2 atm

    final pressure P2 of gas in balloon = 1.9 atm

    final volume V2 of gas in balloon = ?

    Solution:

    This problem will be solved by using Boyle's law equation at constant Temperature.

    The formula used

    P1V1 = P2V2

    As we have to find out Volume, so rearrange the above equation

    V2 = P1V1 / P2

    Put value from the data given

    V2 = 100 mL x 3.2 atm / 1.9 atm

    V2 = 168.4 mL

    So the final Volume of gas in baloon = 168.4 mL
