When 1.93 g of NaCl are added to 114 g of water in a constant pressure calorimeter, the temperature of the solution increases by 3.0O degrees C. Given that the molar mass of NaCl is 58.44 g/mol, and the specific heat of the solution is 4.184 J/g°C, what is the molar enthalpy of solution, AHolution for NaCl in kJ/mol? Do not report units in your answer. Do use proper significant figures and report your answer using the correct sign.
