10g of hydrogen and 64g of oxygen were filled in a steel vessel and exploded.Amount of water produced in this reaction will be

Options

(a) 3 moles
(b) 4 moles
(c) 1 moles
(d) 2 moles

Correct Answer:

4 moles

Explanation:

H₂(2g & 1mol) + 1/2 O₂(16g & 0.5mol) → H₂O(18g & 1mol)
10 g of H₂ = 5 mol
and 64 g of O₂ = 2mol
.·. In this reaction, oxygen is the limiting reagent so amount of H₂O produced depends on that of O₂.
Since of 0.5 mol of O₂ gives 1 mol H₂O
.·. 2 mol of O₂ will gives 4 mol H₂O.
