    Explanation:

    Given:
    Pressure of gas (P1) = 75 cm of Hg
    Mass of gas is doubled

    Solution:

    Boyle's Law:
    According to Boyle's law, at constant temperature, the pressure of a gas is inversely proportional to its volume.

    Mathematically:
    P1V1 = P2V2

    Given:
    Initial pressure P1 = 75 cm of Hg
    Initial mass = m
    Final mass = 2m (doubled)
    Initial volume V1 = Final volume V2 (same volume)

    Using Boyle's Law formula:
    P1V1 = P2V2
    75 * V = P2 * V
    P2 = 75 * 2 = 150 cm of Hg

    Therefore, the new pressure of the gas when its mass is doubled at the same volume and temperature is 150 cm of Hg.
