- Eugenol, the main component of clove oil, can be prepared by heating 2-allyl guaiacol (in the absence of oxygen) to temperatures >205 °C. 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.A certain mineral contains the substance Cu(NO3)2 .Cu2SO4. Cu3N2.
