A $41\mathrm{.}0g$ block of an unknown metal is heated in a hot water bath to $100\mathrm{.}0C.$ When the block is placed in an insulated vessel containing $130\mathrm{.}0g$ of water at $25\mathrm{.}0C,$ the final temperature is $28\mathrm{.}0C.$ Determine the specific heat of the unknown metal. The $c_s$ for water is $4\mathrm{.}18\frac{J}{g}C.$
