8.000 moles of Cl2 (g) react with excess P4 (s) to produce 0.5741 mol of phosphorus trichloride. What is the percent yield for t
Sever21 [200]

Answer:

%Yield ≈ 10.8% w/w

Explanation:

P₄ + 6Cl₂ => 4PCl₃

from equation rxn ratios 8 mol Cl₂ => 8(4/6) mole PCl₃ = 5.33 mole theoretically

Given Actual Yield = 0.5741 mole PCl₃;

%Yield = (Actual Yield / Theoretical Yield)100% = (0.5741/5.33)100% = 10.8%
