    2.72L

    Explanation:

    Data obtained from the question include:

    V1 (initial volume) = 3.40 L

    P1 (initial pressure) = 1.20 atm

    P2 (final pressure) = 1.50 atm

    V2 (final volume) = ?

    Since the temperature remains constant, the gas is simply obeying Boyle's law. Using the Boyle's law equation P1V1 = P2V2, we can easily find the final volume as follow:

    P1V1 = P2V2

    1.2 x 3.4 = 1.5 x V2

    Divide both side by 1.5

    V2 = (1.2 x 3.4) / 1.5

    V2 = 2.72L

    Therefore, the final volume is 2.72L
