3. A 50.0mL sample of 0.600 M NaOH is mixed with 150.0 mL sample of 0.400 M HNO3 in a coffee cup calorimeter. If both solutions were initially at 35.0 °C and the temperature of the resulting solution was recorded as 37.0 °C, determine the AH°rxn (in kJ/mol NaOH). Assume no heat is lost to the calorimeter/surroundings and the density and heat capacity of the resulting solution are the same as water.
