2. Calculate the AHº (on a per mole basis) for the HCI/NaOH neutralization. You may assume that the specific heat and density of the resulting solution to be the same as water. Be sure to use the combined total volumes of HCl and NaOH when calculating the total mass for this reaction. Remember to take into account the moles of limiting reagent when calculating the AH° on a per mole basis. a. Calculate the average value for the molar heat of neutralization for your two trials. b. Given that the literature value for the heat of neutralization of H,O* is - 56.146 kJ/mol, calculate the percent error in your result.
