Zinaida [17]

Answer:

2.9 g

Explanation:

There is some info missing. I think this is the original question.

<em>Ammonium perchlorate is the solid rocket fuel used by the U.S. Space Shuttle. It reacts with itself to produce nitrogen gas, chlorine gas, oxygen gas, water, and a great deal of energy. </em>

<em>What mass of water is produced by the reaction of </em><em>9.6 g</em><em> of ammonium perchlorate?</em>

<em />

Step 1: Given data

Mass of ammonium perchlorate: 9.6 g

Step 2: Write the balanced equation

2 NH₄ClO₄(s) → N₂(g) + Cl₂(g) + 2 O₂(g) + 4 H₂O(l)

Step 3: Calculate the moles corresponding to 9.6 g of ammonium perchlorate

The molar mass of ammonium perchlorate is 117.49 g/mol.

9.6 g \times \frac{1mol}{117.49 g} = 0.082mol

Step 4: Calculate the moles of water formed from 0.082 moles of ammonium perchlorate

The molar ratio of NH₄ClO₄ to H₂O is 2:4. The moles of water formed are 4/2 × 0.082 mol = 0.16 mol

Step 5: Calculate the mass corresponding to 0.16 moles of water

The molar mass of water is 18.02 g/mol.

0.16 mol \times \frac{18.02g}{mol} = 2.9 g
