    a. 392

    Explanation:

    According to Boyles law, the pressure of a fixed mass of a gas at constant temperature is inversely proportional to the volume.

    P1V1=P2V2

    P1=488mm Hg

    P2=757.8mm Hg

    V1=609 mL

    Therefore we use the values above in the formula and get:

    488 mm Hg*609 mL=757.8 mm Hg*V2

    V2 = (488mmHg*609 mL) / 757.8 mm Hg

    =392.177 mL
