You are performing the following acid-base reaction:

NaOH (50.0 mL, 3.75 M) is mixed with H3PO4 (75.0 mL, 3.33 M) at 22°C. Assuming the density of the final solution is equal to the density of water (0.998 g/mL), and assuming no heat loss to the surroundings, if the final temperature of the solution is 29°C, what is the ∆H per mole of H+ reacting? (assume the specific heat of all solutions is 4.184 J/gK)
