When 25.0 mL of 1.0 M H2SO4 is added to 50.0 mL of 1.0M NaOH at 25 °C in a calorimeter, the
temperature of the aqueous solution increases to 33.9 °C. Assuming that the specific heat of the
solution is 4.18 J/g•°C, that the solution density is 1.00 g/mL, and that the calorimeter itself absorbs a
negligible amount of heat, calculate AH (in kJ/mol) for the reaction.
