Question

1.     For an experiment, you have a calorimeter with 350 g of water at 24°C. 175 g of

crystalline ammonium nitrate from a cold pack is placed into the calorimeter. When the ammonium nitrate finishes dissolving in the water, the temperature of the water inside the calorimeter is 5.5°C. The total mass of the solution is 525 g and the specific heat of the solution is 4.18 J/g °C (the same as water). What is the enthalpy of dissolving (DHdissolving) of in J/g ammonium nitrate? Work must be shown in order to earn credit.

Top Answer

Adding ammonium nitrate salt to the water is an endothermic reaction i.e enthalpy or dissolving would be positive and it... View the full answer
