A student was synthesizing aspirin in the lab. Using the amount of limiting reactant, she calculated the mass of aspirin that should form as 5.24g. When she weighed her aspirin product on the balance, it mass was 2.23g. What is the percent yield of the aspirin?
The percent yield of aspirin can be calculated using the following formula:
Percent Yield = (Actual Yield / Theoretical Yield) × 100
Actual yield is the mass of the aspirin product obtained, which is 2.23g. Theoretical yield is the calculated mass of aspirin that should form, which is 5.24g.
Percent Yield = (2.23g / 5.24g) × 100 = 0.4255 × 100 = 42.55%
The percent yield of aspirin is 42.55%.
To calculate the percent yield of the aspirin, we will use the following formula:
Percent Yield = (Actual Yield / Theoretical Yield) x 100
Here, the actual yield refers to the mass of aspirin that was obtained in the lab (2.23g), while the theoretical yield refers to the mass of aspirin that should have been obtained based on the limiting reactant calculation (5.24g).
Using the above information, we can calculate the percent yield:
Percent Yield = (2.23g / 5.24g) x 100
Percent Yield = 0.425 x 100
Percent Yield = 42.5%
Therefore, the percent yield of the aspirin is 42.5%.
To find the percent yield of the aspirin, you need to compare the actual yield (the mass of aspirin obtained in the experiment) to the theoretical yield (the mass of aspirin calculated using the limiting reactant).
The percent yield can be calculated using the formula:
Percent Yield = (Actual Yield / Theoretical Yield) * 100
In this case, the actual yield is 2.23g (the mass of aspirin obtained in the experiment) and the theoretical yield is 5.24g (the mass of aspirin calculated using the limiting reactant).
So, plug in the values into the formula:
Percent Yield = (2.23g / 5.24g) * 100
Simplifying the equation:
Percent Yield = 0.425 * 100
Percent Yield ≈ 42.5%
Therefore, the percent yield of the aspirin in this experiment is approximately 42.5%.
