The salt cesium sulfate is soluble in water. When $23\mathrm{.}2gC{s}_{2}S{O}_4$ is dissolved in $106\mathrm{.}00g$ water, the temperature of the solution decreases from $25\mathrm{.}00C$ to $22\mathrm{.}62C.$ Based on this observation, calculate the dissolution enthalpy, ${}_{\text{d}\text{i}\text{s}\text{s}}H,$ of $C{s}_{2}S{O}_4.$

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.

${}_{\text{d}\text{i}\text{s}\text{s}}H=,\frac{}{m}ol$
