    Answer:

    0.274 L

    Explanation:

    Applying Boyle’s law,

    PV = P’V’…………….. Equation 1

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

    make V’ the subject of the equation,

    V’ = PV/P’…………. Equation 2

    From the question,

    Given: P = 500 mm Hg, V = 500 mL = 0.5 L, P’ = 1.2 atm = 912 mm Hg

    Substitute these values into equation 2

    V’ = (0.5×500)/912

    V’ = 0.274 L

    Hence the new volume is 0.274 L
