How many moles of H₂O are produced when 0.30 mol of C₃H₈ burns completely? (C₃H₈ + 5O₂ → 3CO₂ + 4H₂O)
A.1.2 mol
B.0.30 mol
C.0.075 mol
D.4.0 mol
Explanation
Core Concept
The 1:4 propane-to-water ratio gives 0.30 × 4 = 1.2 mol H₂O. Coefficients scale the product with the reactant.
Correct Answer
A1.2 mol
