Calculate the percent yield of eugenol obtained considering the fact that clove oil is approximately 16-19 % clove by weight of cloves.
isolated eugenol=061g
purity of eugenol in clove oil=99.6% (based on clove oil gas chromatograph)
Estimate the % yeild for eugenol.
Is there a missing decimal point in 061 g?
To calculate the percent yield of eugenol, we need to consider the given information about the weight of cloves, the amount of eugenol obtained, and the purity of eugenol in clove oil.
Step 1: Determine the weight of the cloves
Since clove oil is approximately 16-19% clove by weight of cloves, we can assume that 100% of the weight is represented by the weight of cloves. Let's assume the weight of the cloves is "x" grams.
Step 2: Calculate the weight of eugenol in the cloves
If the weight of cloves is "x" grams, and clove oil is approximately 16-19% clove by weight, the weight of eugenol in the cloves can be calculated as (0.16-0.19) * x grams.
Step 3: Calculate the theoretical yield of eugenol
Given that the weight of isolated eugenol is 0.61 grams, we can assume that this is the theoretical yield of eugenol.
Step 4: Calculate the percent yield of eugenol
The percent yield can be calculated using the formula:
Percent Yield = (Actual Yield / Theoretical Yield) * 100
Substituting the given values:
Percent Yield = (0.61 / (0.16-0.19) * x) * 100
However, we do not have the value of "x" (weight of cloves) in grams, so we cannot calculate the exact percent yield of eugenol without that information.
Note: The given purity of eugenol in clove oil (99.6%) is not directly necessary to calculate the percent yield, as it refers to the purity of eugenol in the oil, not necessarily the amount of eugenol obtained.
To calculate the percent yield of eugenol, you need to compare the actual amount of eugenol obtained with the maximum theoretical amount of eugenol that could be obtained.
First, let's calculate the theoretical maximum amount of eugenol that could be obtained from the weight of clove oil used.
Assuming 16-19% clove content by weight of cloves, let's take the average and consider 17.5% as the clove content. This means that 17.5 grams of cloves would yield 100 grams of clove oil.
Now, we need to calculate the maximum theoretical amount of eugenol in 100 grams of clove oil. Given that the purity of eugenol in the clove oil is 99.6%, we can assume that 99.6 grams of the 100 grams of clove oil is eugenol.
Therefore, the theoretical maximum amount of eugenol that could be obtained is 99.6 grams.
Now, let's calculate the percent yield of eugenol using the actual amount of isolated eugenol.
Percent Yield = (Actual amount / Theoretical maximum amount) x 100
Substituting the values:
Percent Yield = (0.61 g / 99.6 g) x 100
Percent Yield ≈ 0.61%
Therefore, the estimated percent yield of eugenol is approximately 0.61%.
