Problem

-37.0\,\text{kJ}\,\text{mol}^{-1}

. If

2.00\,\text{g}

of LiCl (molar mass

42.39\,\text{g}\,\text{mol}^{-1}

) is dissolved in

200.0\,\text{g}

of water initially at

20.0\,^\circ\text{C}

in an insulating container, assume the specific heat capacity of the solution is

4.18\,\text{J}\,\text{g}^{-1}\,^\circ\text{C}^{-1}

and that the calorimeter absorbs no heat. Calculate the final temperature of the solution.
