Assume that 50.0 mL of 0.400 M HCl and 100.0 mL of 0.200 M CsOH are mixed in a calorimeter. The final temperature after the reaction is 24.28 degrees C and the solutions start out at 22.50 degrees C. The densities of the solutions are all 1.00 g/mL, and the specific heat of the mixture is 4.2 J/ (g x C). Determine the enthalpy change for the neutralization reaction of 1.00 mol of CsOH in the kJ?
