An unknown metal of mass 192 g heated to a temperature of `100^(@)C` was immersed into a brass calorimeter of mass 128 g containing 240 g of water at a temperature of `8.4^(@)C`. Calculate the specific heat of the unknown metal if water temperature stabilizes at `21.5^(@)C`. (Specific heat of brass is `394 J kg^(-1) K^(-1)`)
