Theoretical yield

Question

Liquid ethanol (C 2 H 5 OH) and carbon dioxide gas are produced from the fermentation of solid sucrose (C 12 H 22 O 11 ) and water. 684 grams of sucrose undergoes fermentation and 349 grams of ethanol are produced. What is the theoretical yield for this reaction?

Answer 1

This was a bear to balance; I get 4 C₁₂H₂₂O₁₁ + 4 H₂O --> 16 C₂H₅OH + 16 CO₂. Theoretical yield: (684g C₁₂H₂₂O₁₁) * (1 mol C₁₂H₂₂O₁₁ / 342.3g C₁₂H₂₂O₁₁) * (16 mol C₂H₅OH / 4 mol C₁₂H₂₂O₁₁) * (46.07g C₂H₅OH / 1 mol C₂H₅OH) = 368g C₂H₅OH.
