Calculate the enthalpy (in kJ) per mole of KOH when 3.25 g KOH is added to H2SO4 in a coffee cup calorimeter to make 123.2 mL of total solution with density 1.06 g/mL. Assume the specific heat capacity of the solution is 4.184 J/g°C, that no heat is lost to the surroundings and that the final temperature of the solution is 7.52°C higher than the starting temperature.
