Assume that 100.0 mL of 0.200 M CsOH and 50.0 mL of 0.400 M HCl are mixed in a calorimeter. The solutions start out at 22.50 ∘C, and the final temperature after reaction is 24.28 ∘C. The densities of the solutions are all 1.00 g/mL, and the specific heat of the mixture is 4.2J/(g⋅∘C). Calculate the energy which releases in the process. Express your answer using four significant figures.
