A cube of solid benzene $(C_6{H}_6)$ at its melting point and weighing $10\mathrm{.}0g$ is placed in $15\mathrm{.}0g$ of water at $35C.$ Given that the heat of fusion of benzene is $9\mathrm{.}92k\frac{J}{m}ol,$ to what temperature will the water have cooled by the time all of the benzene has melted?
