When a 5.50g sample of solid sodium hydroxide dissolves in 100.0 g of water in a coffee cup calorimeter, the temperature of rises from 21.6 degrees C to 37.8 degrees C. Calculate Change of heat for the reaction in kJ (also in kJ/mol NaOH) for the solution process. Assume the specific heat of the solution is the same as pure water. Is this an exothermic or endothermic process?
