    Answer: we will solve it using Boyle's law that is:

    P1V1 = P2V2

    Explanation:

    Substituting the given values

    740 torr * 250 mL = 800 torr * V2

    rearranging the equation for V2

    740 torr * 250 mL / 800 torr = V2

    'torr' in numerator cancelled by 'torr' in denominator

    740 * 250 mL / 800 = V2

    V2 = 231.24 mL
