Step-by-step explanation:
Step 1: Define
[RxN - Balanced] C₁₂H₂₂O₁₁ + 12O₂ → 12CO₂ + 11H₂O + Energy
[Given] 448 g C₁₂H₂₂O₁₁ (sucrose)
[Solve] grams CO₂ (carbon dioxide)
Step 2: Identify Conversions
[RxN] 1 mol C₁₂H₂₂O₁₁ → 12 mol CO₂
[PT] Molar Mass of C - 12.01 g/mol
[PT] Molar Mass of H - 1.01 g/mol
[PT] Molar Mass of O - 16.00 g/mol
Molar Mass of C₁₂H₂₂O₁₁ - 12(12.01) + 22(1.01) + 11(16.00) = 342.34 g/mol
Molar Mass of CO₂ - 12.01 + 2(16.00) = 44.01 g/mol
Step 3: Stoich
- [DA] Set up conversion:

- [DA] Multiply/Divide [Cancel out units]:

Step 4: Check
Follow sig fig rules and round. We are given 3 sig figs.
691.119 g CO₂ ≈ 691 g CO₂
