    Answer:

    844.4cm³

    Explanation:

    Using Boyle’s law equation;

    P1V1 = P2V2

    Where;

    P1 = initial pressure (mmHg)

    P2 = final pressure (mmHg)

    V1 = initial volume (cm³)

    V2 = final volume (cm³)

    According to the information in this question,

    V1 = 650cm³

    P1 = 760mmHg

    P2 = ?

    V2 = 10% reduction of V1

    10% of 650 = 10/100 × 650

    65

    V2 = 650 – 65 = 585cm³

    Using P1V1 = P2V2

    P2 = P1V1 ÷ V2

    P2 = (760 × 650) ÷ 585

    P2 = 494000 ÷ 585

    P2 = 844.44

    final pressure (P2) = 844.4cm³
