    The specific heat of the metal is 0.0132 J g^-1 °K^-1

    Explanation:

    The sample of metal absorbs 180.8 J of heat.

    Mass of the metal = 22.44 g

    Temperature increase = Final temperature - initial temperature

    change in temperature = (45 + 273 K) - (21.1 + 273 K) = 318 + 294.1 = 612.1 K

    Specific heat of the metal = ?

    When raising the temperature of a substance, the heat absorbed is calculated using:

    H = m c ΔT

    Rearranging and making c the sunject of the formula, we obtain:

    c = H / m ΔT

    c = 180.8 J / 22.44 g * 612.1 K

    c = 180.8 J / 13735.524 g K

    c = 0.0132 J g^-1 °K^-1

    The specific heat of the metal is 0.0132 J g^-1 °K^-1
