An 8.000 gram sample of solid NH.NO, was mixed with a 200.00 mL sample of water in a coffee cup calorimeter. The water was initially at 20.0°C and the final temperature of the resulting solution was recorded as 17.1°C. Calculate the experimental AHcoln (in units of kJ/mol NH.NO:) for the dissolution of NH NO3 (molar mass = 80.04 g/mol). Assume that no heat is lost to the calorimeter or the surroundings. The density of water is 1.00 g/mL and the...
