If you obtained a percentage yield of 55.1% from a reaction where the theoretical yield was 84 g, what was the actual amount of material you obtained in grams?
Question
If you obtained a percentage yield of 55.1% from a reaction where the theoretical yield was 84 g, what was the actual amount of material you obtained in grams?
Solution
The percentage yield of a reaction is calculated by comparing the actual yield (what you actually got) to the theoretical yield (what you should have gotten, according to the stoichiometry of the reaction).
Here are the steps to calculate the actual yield:
-
Understand the formula: Percentage yield = (Actual yield / Theoretical yield) x 100%
-
Rearrange the formula to solve for the actual yield: Actual yield = (Percentage yield / 100%) x Theoretical yield
-
Substitute the given values into the formula: Actual yield = (55.1% / 100%) x 84 g
-
Perform the calculation: Actual yield = 0.551 x 84 g = 46.3 g
So, if you obtained a percentage yield of 55.1% from a reaction where the theoretical yield was 84 g, the actual amount of material you obtained was approximately 46.3 g.
