A procedure called for 0.50 g of flourenol to be dissolved in 2.0mL of H2O. In lab, 0.60 g was dissolved in 2.0mL of H2O. He then extracted this solution with two, 2.0mL portions of hexane. After combining the hexane extracts as well as evaporating the hexane he had 0.49 g of crystals. Explain what is the theoretical yield and percent recovery?
