Commercial cold packs consist of solid ammonium nitrate and water. NH4NO3 absorbs 3.30 10 2 J of heat per gram dissolved in water. In a coffee-cup calorimeter, 4.40 g NH4NO3 is dissolved in 100.0 g of water at 21.0 ∘C . What is the final temperature of the solution? Assume that the solution has a specific heat capacity of 4.18 J/g⋅K. 3.3 ∘C 20.9 ∘C 17.7 ∘C 24.3 ∘C 20.2 ∘C
