Potassium nitrate, KNO3, has a molar mass of 101.1 g/mol. In a constant-pressure calorimeter, 28.4 g of KNO3 is dissolved in 335 g of water at 23.00 °C. H₂O KNO3(s) →→→ K+ (aq) + NO3(aq) The temperature of the resulting solution decreases to 19.40 °C. Assume that the resulting solution has the same specific heat as water, 4.184 J/(g. °C), and that there is negligible heat loss to the surroundings. How much heat was released by the solution? 9soln = What is the enthalpy of the reaction? AHrxn= kJ kJ/mol
