    Heat gained is equal to the heat lost;

    Heat lost by metal = 5.10 * y * 19.4, where y is the specific heat capacity of the metal.

    = 98.94 y

    Heat gained by water = 20 g * 4.18 j/g * 7.1

    = 593.56 Joules

    Therefore; 98.94 y = 593.56

    y = 593.56/98.94

    = 5.99919 j/g

    ≈ 6.0 j/g

    Therefore, the specific heat capacity of the metal is 6.0 J/g°C
