    Answer: The final pressure is 75 mm Hg.

    Explanation:

    According to Boyle’s law, at constant temperature the pressure of a gas in inversely proportional to volume.

    Since, it is given that the temperature is constant. Hence, formula used is as follows.

    P_{1}V_{1} = P_{2}V_{2}

    Substitute the values into above formula as follows.

    P_{1}V_{1} = P_{2}V_{2}\\750 mm Hg \times 2 L = P_{2} \times 20 L\\P_{2} = \frac{750 mm Hg \times 2 L}{20 L}\\= 75 mm Hg

    Thus, we can conclude that the final pressure is 75 mm Hg.
