Answer:
9.03×10²³ molecules of H₂O
Explanation:
To solve this, we need to propose the reaction
NH₄ClO₄ → ammonium perchlorate
Al → Aluminum
Those are the reactants; the reaction is:
6NH₄ClO₄ + 10Al → 5Al₂O₃ + 3N₂ + 6HCl + 9H₂O
Then, water is one of the products. If we see the reaction, is a redox type.
Ratio is 6:9. In conclussion:
6 moles of ammonium perchlorate can produce 9 moles of H₂O
Then 1 mol of salt, may produce (1 . 9)/6 = 1.5 moles of water
Let's count the molecules:
1.5 mol . 6.02×10²³ molecules /mol = 9.03×10²³ molecules of H₂O
