100.0 mL of 1.020 M HCl and 50.0 mL of 2.040 M NaOH, each at 24.53ºC, are mixed in a Styrofoam cup calorimeter. What is the final temperature of the mixture if the heat of acid-base neutralization (?Hneut) = ?57 kJ per mole of H2O formed? (Assume density of the solution = 1.00 g/mL and specific heat of the solution = 4.184 J/g•ºC, and assume an insignificant heat capacity of the Styrofoam cup)
