Consider the dissolution of ${\mathrm{CaCl}}_2$ : ${\mathrm{CaCl}}_2(s)?{\mathrm{Ca}}^{2+}(aq)+2{\mathrm{Cl}}^{?}(aq)?H=?81.5\mathrm{kJ}$ An 11.5-g sample of ${\mathrm{CaCl}}_2$ is dissolved in $121\mathrm{g}$ water, with both substances at $25.0^{?}\mathrm{C}$. Calculate the final temperature of the solution assuming no heat loss to the surroundings and assuming the solution has a specific heat capacity of $4.18\mathrm{J}/{}^{?}\mathrm{C}?\mathrm{g}$. Temperature $={}^{?}\mathrm{C}$
