    2.84 j/g.°C

    Explanation:

    Given dа ta:

    Mass of mercury = 54 g

    Initial temperature = 25°C

    Final temperature = 195°C

    Heat absorbed = 26110 j

    Specific heat of mercury = ?

    Solution:

    Formula:

    Q = m. c. ΔT

    Q = amount of heat absorbed or released

    m = mass of given substance

    c = specific heat capacity of substance

    ΔT = change in temperature

    ΔT = T2 - T1

    ΔT = 195°C - 25°C

    ΔT = 170 °C

    Q = m. c. ΔT

    c = Q / m. ΔT

    c = 26110 j / 54 g. 170 °C

    c = 26110 j / 9180 g.°C

    c = 2.84 j/g.°C
