TUTOR Coffee Cup Calorimetry: Heat of Solution 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.
