A student was asked to determine the enthalpy of solution of KCIO3 in water using Styrofoam calorimetry. Calibration was performed by mixing 8.00 mL 0.050 M HCl with 2.00 mL 0.200 M NaOH. The neutralization reaction (AH = -55.85 kJ/mol) was accompanied by a temperature change from 25.0 to 28.3°C. Using the same calorimeter, 0.300 g KCIO3 (MW: 122.55) was dissolved in water and the temperature was observed to change from 23.6 to 17.3°C. (Assume that the total volume of the mixture in calibration is the same in the enthalpy measurement) What is the calorimeter constant in kJ/°C? Answer: What is the enthalpy of dissolution of KCIO3 in kJ/mol? Answer:
