    Answer: 1.2 Liters

    Explanation:

    Given that,

    Original volume of oxygen V1 = 2.1 L

    Original pressure of oxygen P1 = 375 torr

    New pressure of oxygen P2 = 663 torr

    New volume of oxygen V2 = ?

    Since pressure and volume are given while temperature is constant, apply the formula for Boyle's law

    P1V1 = P2V2

    375 torr x 2.1L = 663 torr x V2

    787.5 torr L = 663 torr x V2

    V2 = 787.5 torr L / 663 torr

    V2 = 1.188L (Round the volume to the nearest tenth as in 1.2L)

    Thus, the volume of oxygen is 1.2 liters when the pressure is 663 torr.
