How many moles of carbon dioxide (CO2) will form when 16.3 moles of water (H2O) form in the reaction below?

Question

C₃H₈ + 5 O₂  →  3 CO₂  +  4 H₂O

Answer 1

C₃H₈ + 5 O₂  →  3 CO₂  +  4 H₂O .. balanced equation

Use the stoichiometry of the balanced equation and dimensional analysis:

16.3 mols H₂O x 3 mol CO₂ / 4 mols H₂O = 12.2 mols CO₂
