One mole of propane is mixed with five moles of oxygen. The mixture is ignited and the propane burns completely. What is the volume of the products at s.t.p?
(G.M.V = 22.4 dm³ mol^-1)

Correct Answer: Option B

Explanation

C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
When the mixture is ignited CO₂ is collected as product. From the equation 33 moles of CO₂ is produced which equals 3 x 2.4 dm³ = 67.2 dm³ at S.T.P
