QUESTION 23 A student obtains two solutions both of which are at 21°C. One solution is 50.0 milliliters of 0.10 M potassium hydroxide. The other is 50.0 milliliters of 0.10 M nitric acid. The student combines these solutions in a calorimeter. The maximum temperature reached is 27 C. Assuming that no heat was lost to the calorimeter, calculate the enthalpy of this reaction in kJ/mol. The specific heat of water is 4.184 J/g-K.
