Ammonium perchlorate is a powerful solid rocket fuel, used in the Space Shuttle boosters. It decomposes into nitrogen gas, chlorine gas, oxygen gas and water vapor, releasing a great deal of energy. Calculate the moles of ammonium perchlorate needed to produce of chlorine. Be sure your answer has a unit symbol, if necessary, and round it to significant digits.

0.18 mol

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

Ammonium perchlorate is a powerful solid rocket fuel, used in the Space Shuttle boosters. It decomposes into nitrogen gas, chlorine gas, oxygen gas and water vapor, releasing a great deal of energy. Calculate the moles of ammonium perchlorate needed to produce 0.090 mol of chlorine. Be sure your answer has a unit symbol, if necessary, and round it to 2 significant digits.

First, we write the balanced chemical equation.

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

The molar ratio of NH₄ClO₄ to Cl₂ is 2:1. The moles of NH₄ClO₄ required to produce 0.090 mol of Cl₂ are:

0.090 mol Cl₂ × (2 mol NH₄ClO₄/1 mol Cl₂) = 0.18 mol NH₄ClO₄
