(A) If 215 g P₄ is allowed to react with 725 g Cl₂ in the reaction in Example 4-11, how many grams of PCl₃ are formed?

(B) If 1.00 kg each of PCl₃, Cl₂ and P₄O₁₀ are allowed to react, how many kilograms of POCl₃ will be formed?

6 PCl₃(l) + 6 Cl₂(g) + P₄O₁₀(s) → 10 POCl₃(l)

Example 4-11

Phosphorus trichloride, PCl₃ is a commercially important compound used in the manufacture of pesticides, gasoline additives, and a number of other products. A ball-and-stick model of PCl₃ is shown below. Liquid PCl₃ is made by the direct combination of phosphorus and chlorine.

What is the maximum mass of PCl₃ that can be obtained from 125 g P₄ and 323 g Cl₂?
