When a 9.55-g sample of solid sodium hydroxide dissolves in 100.0 g of water in a coffee-cup calorimenter (figure 5.17), the temperature rises from 23.6 ?C to 47.4 °C. calculate (in kJ/mol NaOH) for the solution process

Assume that the specific heat of the solution is the same as that of pure water.
