Assuming the solution has a heat capacity of 4.18 jdegc, Ask an Expert

Academics

In a coffee-cup calorimeter, 1.70 g of NH4NO3 is mixed with 71.0 g of water at an initial temperature of 25.00°C. After dissolution of the salt, the final temperature of the calorimeter contents is 23.95°C. Assuming the solution has a heat capacity of 4.18 J/°C · g and assuming no heat loss to the calorimeter, calculate the enthalpy change for the dissolution of NH4NO3 in units of kJ/mol.
