    Answer:

    2.38 kg

    Explanation:

    by definition, weight in physics is the force of gravity (Fg)

    Fg = mass x gravity or mg

    gravity is 9.8 m/s^2

    N = kg m/s^2

    Fg = mg

    23.3 kg m/s^2 = 9.8 m/s^2 x m

    23.3 kg m/s^2 / 9.8 m/s^2 = m    >>> m/s^2 cancel out

    23.3/9.8 = 2.37755 kg

    m = 2.38 kg
