When NaCl dissolves in water, the ΔHsol = +3.9 kJ/mol. Predict the volume of a NaCl solution with molarity = 2.5 mol/L that would experience an energy change of 45.6 kJ? Note: specific heat capacity H20 = 4.18 J/goC

Your answer should follow the format:

a) mols of NaCl to experience 45.6 kJ energy change

b) volume of 2.5M NaCl required (with units)
