    0.00353J/g/°C

    Explanation:

    I will assume the temperature of the ice to be approximately 0°C.

    Moreover, Heat of fusion of water is 6kJ

    Amount of heat used to melt 5.3g of ice = 5.3 x 6 / 18

    =1.767g°C

    Therefore

    1.767 = 25 x specific heat cap. x 200

    Specific heat cap. = 1.767 / (25x200)

    = 0.00353J/g/°C
