• Percent
• actual
• stoichiometry
• theoretical

What is the formula for percent yield?

• $\frac{Actual}{Theoretical}\times100$
  

• $\frac{Theoretical}{Actual}\times100$
  

• $\frac{Actual\times Theoretical}{100}$

• $\frac{100}{Actual\times Theoretical}$

P₄ + 6Cl₂ --> 4PCl₃ 
The reaction of 75.0g P₄ with excess chlorine gas produces 110g PCl₃ in lab. Find the theoretical yield and calculate percent yield for the reaction. 

• 78%
• 64%
• 27%
• 33%
