Calculate the enthalpy change (ΔH) for the dissolution of 10 grams of NaOH in 100 mL of water, given that the final temperature after mixing is 28°C and the initial temperature of water was 25°C. The specific heat capacity of water is 4.18 J/g°C. The molar mass of NaOH is 40.00 g/mol and the enthalpy of dissolution for NaOH is -44.51 kJ/mol.
