An unknown metal of mass 192 g heated to a temperature of \[100{}^\circ C\] was immersed into a brass calorimeter of mass 128 g containing 240 g of water at a temperature of \[8.4{}^\circ C\]. Calculate the specific heat (in \[J\,\,k{{g}^{-1}}{{K}^{-1}}\]) of the unknown metal if water temperature stabilizes at \[21.5{}^\circ C\]. (Specific heat of brass is 394 \[J\,\,k{{g}^{-1}}{{K}^{-1}}\])
