Solid potassium chlorate (kclo3) decomposes into potassium chloride and oxygen gas when heated. how many moles of oxygen form wh
IrinaVladis [17]

Answer:

  • <u>0.665 mol of O₂.</u>

Explanation:

<u>1. Molecular chemical equation:</u>

  • 2 KClO₃(s) → 2 KCl(s) + 3 O₂(g)

<u>2. Mole ratios:</u>

  • 2 mol KClO₃ : 2 mol KCl : 3 mol O₂

<u>3. Number of moles of KClO₃</u>

  • Number of moles = mass in grams / molar mass

  • Molar mass of KClO₃ = 122.55 g/mol

  • Number of moles of KClO₃ = 54.3 g / 122.5 g/mol ≈ 0.44308 mol

<u>3. Number of moles of O₂</u>

As per the theoretical mole ratio 2 mol of KClO₃ produce 3 mol of O₂, then set up a proportion to determine how many  moles of O₂ will be produced from 0.44038 mol of KClO₃.

  • 3 mol O₂ / 2 mol KClO₃ = x / 0.44038 mol KClO₃

  • x = (3 / 2) × 0.44308 mol O₂ = 0.6646 mol O₂

Round to 3 significant figures: 0.665 mol of O₂ ← answer
