When 2.89 g of AX (s) dissolves in 125.3 g of water in a coffee-cup calorimeter the temperature rises from 21.4 °C to 33.6 °C. Calculate the enthalpy change (in kJ/mol) for the solution process. AX (s) → A*(aq) + X- (aq) Assumptions for this calculation: · The specific heat of the solution is the same as that of pure water (4.18 J/gK) • The density of water = 1.000 g/mL · The liquid's final volume is not changed by adding the solid · The calorimeter loses only a negligible quantity of heat. The formula weight of AX = 59.1097 g/mol. Be sure you include the correct sign for the enthalpy change. Note: Do not use scientific notation or units in your response. Sig figs will not be graded in this question, enter your response to four decimal places.
