Percent yield concept

The ______________ yield is the maximum amount of product possible in a reaction. This determines the amount of product that should be produced in a perfect setting

• Percent
• actual
• stoichiometry
• theoretical

When reacting Na with Cl₂, we calculated that the theoretical yield should be 13 grams. Our actual yield was 12.5 grams. What is the percent yield?

• 90.4%

• 104%

• 96.15%

• 1.04%

Theoretical yield = 73g
Actual yield = 62g
Calculate the percent yield.

• 1.16%
• 116%
• 85%
• 76%

What is the formula for percent yield?

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

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

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

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

CH₄  +  2O₂  →  CO₂  +  2H₂O
24 grams of CH₄ was added to the above reaction. Calculate the theoretical yield of CO₂.

• 66 grams
• 132 grams
• 33 grams
• 8.72

7. The amount of product that is produced when a chemical reaction is carried out in a laboratory is called the _________ yield.

• actual

• theoretical

• percent

In a lab, a scientist calculates that his reaction should produce 12.3 grams of product in his experiment. When he is finished collecting his product it weighs 10.1 grams. Which answer choice(s) correctly identifies the variables

• Actual Yield: 12.3 g

• Theoretical Yield 12.3 g

• Actual Yield: 10.1 g

• Theoretical yield 10.1 g
