You mix 125 mL of 0.170 M CsOH with 50.0 mL of 0.425 M HF in a coffee-cup calorimeter, and the temperature of both solutions rises 20.40 degrees C before mixing to 22.37 degrees C after the reaction. CsOH(aq) + HF(aq) → CsF(aq) + H2O(l)
What is the enthalpy of reaction per mole of CsOH? Assume the densities of the solution are all 1.00 g/mL, and the specific heat capacities of the solutions are 4.2 J/g . K.
