When 20.0 mL of 0.200 M AgNO₃ and 30.0 mL of 0.100 M NaCl, both at 24.72°C, are mixed in a coffee-cup calorimeter, AgCl precipitates and the temperature of the mixture increases to 25.65°C. Calculate ?H in kJ per mole of AgCl(s) produced. (Assume that the total volume is the sum of the volumes and that the density and spe- cific heat capacity of the solution are the same as for water.)
