Phosphine, PH₃, a reactive and poisonous compound, reacts with oxygen as follows: 4PH₃(g) + 8O₂(g) $\rightarrow$P₄O₁₀(s) + 6H₂O(g) If you need to make 6.5 moles of P₄O₁₀, how many moles of PH₃is required for the reaction?

Question

Quizplus · Accepted Answer

According to the balanced equation, 4 moles of PH₃ produce 1 mole of P₄O₁₀. Therefore, to produce 6.5 moles of P₄O₁₀, you need 4 times 6.5 moles of PH₃, which is 26 moles.
