What is the final temperature of a system if $17\mathrm{.}00g$ of gold at $90\mathrm{.}0C$ is placed in $17\mathrm{.}00g$ of water at $21\mathrm{.}00C.$ The molar heat capacity of gold is $25\mathrm{.}41\frac{J}{\text{m}\text{o}\text{l}*C}$ and the heat capacity of water is $4\mathrm{.}18\frac{J}{g*C}.$
