    Answer:

    420 L

    Explanation:

    Applying Boyle’s Law,

    PV = P’V’……………….. Equation 1

    Where P = Initial pressure, P’ = Final pressure, V = Initial volume, V’ = Final volume.

    make V’ the subject of the equation

    V’ = PV/P’……………….. Equation 2

    From the question,

    Given: P = 720 mmHg, V = 350 L, P’ = 600 mmHg

    Substitute these values into equation 2

    V’ = (720×350)/600

    V’ = 252000/600

    V’ = 420 L
