TUTOR Coffee Cup Calorimetry: Heat of Solution

The salt calcium bromide is soluble in water. When $1\mathrm{.}44gCaB{r}_2$ is dissolved in $103\mathrm{.}00g$ water, the temperature of the solution increases from $25\mathrm{.}00C$ to $26\mathrm{.}66C.$ Based on this observation, calculate the dissolution enthalpy, ${}_{\text{d}\text{i}\text{s}\text{s}}H,$ of $CaB{r}_2.$

Assume that the specific heat capacity of the solution is $4\mathrm{.}184J{g}^{-1}{C}^{-1}$ and that the energy transfer to the calorimeter is negligible.
