When a 6.50-g sample of solid sodium hydroxide dissolves in 100.0 g of water in a coffee-cup calorimeter, the temperature rises from 21.6 degrees c to 37.8 degrees c. calculate delta h (in kj/mol naoh) for the solution process. assume that the specific heat of the solution is the same as that of pure water.
