Two solutions, initially at 24.69 °C, are mixed in a coffee cup calorimeter (Ccal = 105.5 J °C-1). When a 200.0 mL volume of 0.100 mol L-1 AgNO3 solution is mixed with a 100.0 mL sample of 0.100 mol L-1 NaCl solution, the temperature in the calorimeter rises to 25.16 °C. Determine the DrH°, in units of kJ mol-1. Assume that the density and heat capacity of the solutions is the same as that of water.

Hint: Write a balanced reaction for the process.

◦ -25 kJ mol-1
◦ -78 kJ mol-1
◦ -52 kJ mol-1
◦ -32 kJ mol-1
◦ -64 kJ mol-1
