A $57\mathrm{.}0$ g block of an unknown metal is heated in a hot water bath to $100\mathrm{.}0\backslash$deg C$.$ When the block is placed in an insulated vessel containing $130\mathrm{.}0$ g of water at $25\mathrm{.}0\backslash$deg C$,$ the final temperature is $28\mathrm{.}0\backslash$deg C$.$ Determine the specific heat of the unknown metal. The cs for water is $4\mathrm{.}18$ J$/$g$\backslash$deg C$.$
