Compute the enthalpy change for the dissolution of ammonium, Ask an Expert

Academics

1.30 grams of ammonium nitrate is combined with 74.0 grams of H₂O In a coffee-cup calorimeter, at an initial temperature of 25 degree celsius. The final temperature of the calorimeter contents =23.53°C After dissolution of the salt,. Assuming the solution has a heat capacity = 4.18 J/°C · g (assuming no heat loss to the calorimeter,) compute the enthalpy change for the dissolution of ammonium nitrate express your answers in units of kJ/mol.
