    Answer:

    0.1 mole of CH₄

    Explanation:

    From the question given above, the following data were obtained:

    Volume of CH₄ = 2.24 L

    Number of mole of CH₄ =?

    The number of mole of CH₄ can be obtained as follow:

    Recall:

    1 mole of a gas occupy 22.4 L at stp. This implies that 1 mole of CH₄ occupies 22.4 L at stp.

    22.4 L = 1 mole of CH₄

    Therefore,

    2.24 L = 2.24 × 1 mole of CH₄ / 22.4

    2.24 L = 0.1 mole of CH₄.
