The conclusion of the student would be that the dissolution of ammonium nitrate is endothermic.
<h3>What are endothermic reactions?</h3>
They are reactions in which heat is absorbed from the surrounding. The consequence is that the reaction mixture's temperature is always lower.
Thus, the energy of the products is always higher than the energy of the reactants in endothermic reactions.
For endothermic reactions, the enthalpy change is always positive.

Answer:
The correct answer to the following question will be "0.0013%".
Explanation:
The given values are:
Weight of an empty dish = 1.0041 ± 0.0002 g
Weight of dish + sodium chloride (NaCl) = 3.2933 ± 0.0002 g
Weight of NaCl = 2.2892 ± 0.0002 g
Now,
Volume of the solution = 500.00 ± 0.05 ± 0.0002
= 500.00 ± 0.0502 ml
So,
Molarity = 
On putting the values in the above formula, we get
