In practice, however, it is most cost-effective to extract eugenol from cloves, its natural source. Given a weight percentage of eugenol in cloves at 15.0%, calculate the minimum mass of cloves one needs to obtain 8.00 g of eugenol as a product. Report your answer (as a mass in grams, without units) with three significant digits.
- Extraction of Caffeine Post-lab 5. On the report sheet, you calculated your percent recovery of caffeine. a. If your percent was less than 90%, give at least one reason why it was less. b. A group of students have their percent yield more than 100%, give at least one reasonwhy it was more than 100%. Do NOT simply say “human error.” Be specific about the typesof errors (human or otherwise) that may have occurred, leading to a recovery more than eorequal to 100% (Is this possible Why?) 6. Based on what you observed during this experiment, is dichloromethane denser OR lessdense than water? Explain your reasoning. 7. Based on what happened in this experiment, is caffeine more soluble in water OR moresoluble in dichloromethane?
