Consider the following acid-base neutralization reaction of nitric acid and sodium hydroxide:
NaOH(aq) + HNO₃(aq) → NaNO₃(aq) + H₂O(1)
You want to measure the enthalpy in kJ/mol. To do this, you first get a coffee cup calorimeter and calibrate it (you get a Coal of 19.3 J/°C for your calorimeter). Then, you combine 55.0 mL of 0.240 M NaOH and 55.0 mL of 0.350 M HNO3. The temperature of the solution starts at 18.9°C and then rises to 19.5 °C. The density of the solution is 1.01 g/mL and it has a heat capacity of 4.02 J/(g*C). What is the enthalpy of reaction in kJ/mol?
