Use the following information to answer the next question. A 100ml sample of 0.500 mol/LNiSO₄(aq) is mixed with 50ml excess NaOH(aq), both initially at 22.3 ∘C. If the enthalpy of neutralization is −54.9 kJ/mol for NiSO 4, calculate the final temperature of the solution, assuming that its density and heat capacity is identical to that of water.
