Based on the amounts of reactants used the calculated amount of product that can form for a given reaction was 20.76 g. When the reaction was carried out in a laboratory 17.34 g of product was recovered. What is the percent yield for this reaction?
A
119.7%
B
83.53%
C
0.8353
D
16.47%
Verified step by step guidance1
Identify the theoretical yield, which is the maximum amount of product that can be formed from the given amounts of reactants. In this problem, the theoretical yield is given as 20.76 g.
Identify the actual yield, which is the amount of product actually recovered from the reaction. In this problem, the actual yield is given as 17.34 g.
Use the formula for percent yield: \( \text{Percent Yield} = \left( \frac{\text{Actual Yield}}{\text{Theoretical Yield}} \right) \times 100 \% \).
Substitute the actual yield (17.34 g) and the theoretical yield (20.76 g) into the percent yield formula.
Calculate the percent yield by performing the division and then multiplying by 100 to convert the result into a percentage.
