The AH for the solution process when solid sodium hydroxide dissolves in water is 44.4 kJ/mol. When a 10.9-g sample of NaOH dissolves in 214 g of water in a coffee-cup calorimeter, the temperature increases from 23.0°C to °C. Assume that the solution has the same specific heat as liquid water, ie., 4.18 J/g-K. The molar mass of sodium hydroxide is 39.997 g/mol.
