Insoluble Li2Co3 (s) precipitates when solutions of Na2Co3 (aq) and LiCl (aq) are mixed. To measure the enthalpy change, 250. mL of 0.80 M Na2Co3 (aq) and 250. mL of 1.6 M LiCl (aq) are mixed in a coffee-cup calorimeter. The temperature of the mixture rises by 1.6 °C. Calculate the enthalpy change for the precipitation of Li2Co3 (s) in kJ/mol. (Assume the density of the solution is 1.0 g/mL, and its specific heat capacity is 4.2 J/g · K.)
