Answer:
<u><em></em></u>
- <u><em>3.42 moles</em></u>
Explanation:
By the law of conservation of energy, assuming no losses of heat to the surroundings, <em>the amount of heat consumed by the dissolution of the ammonium nitrate is equal to the amount of heat released from the water.</em> This is, the ammonium nitrate absorbs all the heat it needs to break the ions apart and get dissolved from the water in which it is being dissolved.
Thus:
↑ ↑ ↑
heat released number of moles molar heat of solution
from water of NH₄NO₃ for NH₄NO₃
Solve for n and compute:
- n = 88.0kJ / (25.7kJ/mol) = 3.42 moles ← answer
Answer:
in 2.5 mole SO42 there are 25 Eq
