    The answer to your question is V2 = 0.203 kPa

    Explanation:

    Data

    Volume 1 = V1 = 1l

    Pressure 1 = P1 = 101.3 kPa

    Volume 2 = V2 = ?

    Pressure 2 = 500 kPa

    Process

    - Use the Boyle's law to solve this problem

    P1V1 = P2V2

    -Solve for V2

    V2 = P1V1/P2

    -Substitution

    V2 = (101.3 x 1) / 500

    -Simplification

    V2 = 101.3 / 500

    -Result

    V2 = 0.203 kPa
