Stoichiometric Calculations

Question

C₃H₈(g) + 5O₂(g) → 3CO₂(g) + 4H₂O(g).

Using your balanced equation, If 15 moles of Propane Gas (C₃H₈) react with excess Oxygen gas, how many moles of water will be formed?

Answer 1

Use the mole ratios in the balanced equation along with dimensional analysis...

15 mols C₃H₈ x 4 mols H₂O / 1 mol C₃H₈ = 60 moles H₂O
