A student placed 25.2 mL of 2.7 M HNO3 in a coffee cup calorimeter, noted that the temperature was 21.0 °C, and added 50.3 mL of 1.3 M LiOH , also at 21.0 °C. The mixture was stirred quickly with a thermometer, and its temperature rose to 33.1 °C. Calculate the enthalpy of reaction in joules. Assume that the specific heats of all solutions are 4.18 J g-1 K-1 and that all densities are 1.00 g mL-1. Calculate the enthalpy of reaction per mole of acid (in units of kJ mol-1).
