    Answer: 1.375 atm

    Explanation:

    Given that,

    Original volume V1 = 2.0 L

    original pressure P1 = ?

    New volume V2 = 5.5L

    New pressure P2 = 0.5 atm

    Since pressure and volume are involved while temperature is constant, apply Boyle's law

    P1V1 = P2V2

    P1 x 2.0 L = 0.5 atm x 5.5L

    P1 x 2.0 L = 2.75 atmL

    P1 = 2.75 atmL / 2.0 L

    P1 = 1.375 atm

    Thus, the original pressure of the hydrogen gas is 1.375 atm
