Calculate the enthalpy change of mixing 50 mL of 1 M HCl with 50 mL of 1 M NaOH at 25°C. It is known that the standard enthalpies of formation of HCl and NaOH are -92.3 kJ/mol and -469.2 kJ/mol, respectively. Assume that the heat capacity of the mixture is 4.18 J/g°C and the density of the solution is 1 g/mL.
