P₄ + 5O₂ → 2P₂O₅
OR: Mole ratio P₄ : P₂O₅ = 1 : 2
No. of moles of P₂O₅ produced = 3 mol
No. of moles of P₄ needed = (3 mol) × (1/2) = 1.5 mol
(Check: Mole ratio P₄ : P₂O₅ = (1.5 mol) : (3 mol) = 1 : 2)
OR: Mole ratio P₄ : P₂O₅ = 1 : 2
No. of moles of P₂O₅ produced = 3 mol
No. of moles of P₄ needed = (3 mol) × (1/2) = 1.5 mol
(Check: Mole ratio P₄ : P₂O₅ = (1.5 mol) : (3 mol) = 1 : 2)
