1.
C₁₀H₈ + 12O₂ → 10 CO₂ + 4H₂O
Mole ratio O₂ : CO₂ = 12 : 10
Moles of CO₂ produced = (8 mol) × (10/12) = 6.7 mol

2.
C₁₀H₈ + 12O₂ → 10 CO₂ + 4H₂O
Mole ratio C₁₀H₈ : CO₂ = 1 : 10
Moles of CO₂ produced = (4 mol) × 10 = 40 mol
C₁₀H₈ + 12O₂ → 10 CO₂ + 4H₂O
Mole ratio O₂ : CO₂ = 12 : 10
Moles of CO₂ produced = (8 mol) × (10/12) = 6.7 mol

12/10 =8/x x=6.66 moles of CO2
1/10 =4/x x=40 moles of CO2
1/10 =4/x x=40 moles of CO2
