Answer:
2.94 g of water are produced by this decomposition
Explanation:
We need to determine the reaction to solve this problem:
The reactant is the ammonium perchlorate
The products are N₂, Cl₂, O₂ and H₂O
The reaction is: 2NH₄ClO₄ → N₂ + Cl₂ + 2O₂ + 4H₂O
We convert the mass of the reactant to moles:
9.6 g . 1 mol / 117.45 g = 0.0817 moles
Ratio is 2:4. Let's make a rule of three:
2 moles of perchlorate produce 4 moles of water.
Then, 0.0817 moles of perchlorate will produce (0.0817 . 4)/2 = 0.163 moles
We convert the moles of produced water, to mass (g)
0.613 mol . 18 g / 1mol = 2.94 g
