As Wile E. Coyote ices his wounds and plans his next move, he wants to measure the enthalpy change for this reaction (maybe he's smarter than he seems!). 1.50 g of NH,NOz is dissolved in enough water to make a solution with a mass of 28.5 g. The initial temperature is 26.2°C and the final temperature (after the solid dissolves) is 21.1 °C. Part A Based on the information given, what is the total heat (gran) associated with the dissolution of the NH,NO3? You may assume that the solution that forms has a heat capacity equivalent to water, 4.184 J -g.° C Express your answer to two significant figures.

To no one's surprise, the only one who's been getting burned is Wile E. Coyote. Good thing he has a few ACME brand instant cold packs! These cold packs contain ammonium nitrate and water, separated by a thin plastic divider. When the divider is broken, the ammonium nitrate dissolves according to the following endothermic reaction: NH,NO3(s) → NH,*(aq) + NO3 (ag) As Wile E.
