when 4.50g sample of solid sodium hydroxide dissolves in 80.0g of water in a coffee cup calorimeter, the temperature rises from 23.8Â°c to 35.2Â°c.

calculate H (in kj/mol NaOH) for the solution process

NaOH (s)â¡Na+(aq) + OH- (aq)

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