Reference no: EM13192115

When a 4.25-g sample of solid ammonium nitrate dissolves in 60.0g of water in a coffee-cup calorimeter, the temperature drops from 22.0 degree C to 16.9 degree C.

Part A)

Calculate ?H (in kJ/mol NH4NO3) for the solution process
NH4NO3(s)?NH+4(aq)+NO?3(aq)

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

Part B) Is this process endothermic or exothermic?
