When 2.708 g of AX (s) dissolves in 121.5 g of water in a coffee-cup calorimeter the temperature rises from 23.1°C to 33.9 °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 = 591097 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 the unrounded value. Carmen may add or remove zeros from your response, your submission will still be graded correctly if this happens.
