- In a neutralization reaction in a well-insulated calorimeter, 112.9 g of 1.2915 M NaOH were added to 129.1 g of 1.1294 M HCI. The following data were obtained. Assume the density of each solution is 1.00 g/mL. The temperature of the solution rose 8.10 °C. a. Assuming the calorimeter, thermometer, and stirrer have a negligible impact on the AHron, calculate the AHn (in kJ) for this reaction. - raction =9 sdution b. Calculate the AHrn per mole of NaOH reacted. c. If the Styrofoam calorimeter (s thermometer (s = 0.840 J/g °C) weighs 20.0 g, and the aluminum stirrer (s = 0.900 J/g °C) weighs 10.0 g, calculate the AHren per mole of NaOH reacted. 1.131 J/g °C) weighs 30.0 g, the glass %3D %3D
