3.3.1 Calculating percentage yield

• What does percentage yield indicate in a chemical reaction?

  It shows the actual product obtained versus expected
• What is the formula for calculating percentage yield?

  • Percentage Yield = (Actual Yield / Theoretical Yield) × 100%
• What does the actual yield represent in an experiment?

  Amount of product obtained in grams or moles
• How is percentage yield calculated?

  By dividing actual yield by theoretical yield
• What does a percentage yield indicate in a chemical reaction?

  It shows the efficiency of the reaction
• If the actual yield is 4 grams and the theoretical yield is 5 grams, what is the percentage yield?

  80%
• What are the definitions of actual yield and theoretical yield?

  • Actual Yield: Amount of product obtained in the experiment
  • Theoretical Yield: Amount of product calculated from stoichiometry
• What is the actual yield in a chemical reaction?

  The amount of product obtained in the lab
• How do you plug values into the percentage yield formula?

  1. Identify Actual Yield and Theoretical Yield
  2. Substitute values into the formula:

  $\text{Percentage Yield} =$$\frac{\text{Actual Yield}}{\text{Theoretical Yield}} \times 100\%$
• If the actual yield is 27.2 grams and the theoretical yield is 34 grams, what is the percentage yield?

  $\text{Percentage Yield} =$$\frac{27.2}{34} \times 100\%$
• What values are needed to calculate percentage yield?

  • Actual Yield
  • Theoretical Yield
• If the actual yield is 30 grams and the theoretical yield is 40 grams, what is the percentage yield?

  75%
• What are the two types of yield in a chemical reaction?

  • Actual Yield: Amount obtained in the lab
  • Theoretical Yield: Maximum calculated from stoichiometry
• Why is the theoretical yield important in chemistry?

  It represents the maximum possible product yield
• What are the components of the percentage yield formula?

  • Actual Yield: Amount obtained in grams or moles
  • Theoretical Yield: Maximum possible amount according to stoichiometry
• How do you calculate the percentage yield in a chemical reaction?

  Percentage Yield = (Actual Yield / Theoretical Yield) × 100%
• What is the formula for calculating percentage yield?

  $\text{Percentage Yield} =$$\frac{\text{Actual Yield}}{\text{Theoretical Yield}} \times 100\%$
• How do you calculate the percentage yield using the given actual and theoretical yields?

  Use $\text{Percentage Yield} =$$\frac{27.2}{34} \times 100\%$
• What is the theoretical yield in a chemical reaction?

  The maximum amount of product from stoichiometry
• What values are summarized in the table for percentage yield calculation?

  • Actual Yield: 27.2 grams
  • Theoretical Yield: 34 grams
  • Percentage Yield: 80%
• What does a percentage yield of 80% signify?

  It indicates that 80% of expected product was obtained
