    Answer: Option C) 0.64kPa

    Explanation:

    Given that,

    Original volume V1 = 11.2 L

    original pressure P1 = 0.860kPa

    New volume V2 = 15.0 L

    New pressure P2 = ?

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

    P1V1 = P2V2

    0.860 kPa x 11.2 L = P2 x 15.0L

    9.632 kPaL = P2 x 15.0L

    P2 = 9.632 kPaL / 15.0L

    P2 = 0.64 kPa

    Thus, the pressure of the gas is 0.64kPa
