Phosphine, PH₃, a reactive and poisonous compound, reacts with oxygen as follows: 4PH₃(g)+ 8O₂(g)→ P₄O₁₀(s)+ 6H₂O(g)If 15.0 g of phosphine reacts with sufficient oxygen, how many grams of P₄O₁₀ will be formed?

Question

Quizplus · Accepted Answer

Use stoichiometry to find the moles of P₄O₁₀ produced: 1 mole of PH₃ reacts to form 1/4 mole of P₄O₁₀ 15.0 g PH₃ x (1 mol PH₃ / 34.02 g PH₃) x (1/4 mol P₄O₁₀ / 1 mol PH₃) x (680.64 g P₄O₁₀ / 1 mol P₄O₁₀) = 31.3 g P₄O₁₀
