In an experiment involving the extraction of essential oils from a plant, 7.5 mL of benzene (C6H6, 78.11 g/mol) was mixed with 25.00 mL of hexane (C6H14, 86.18 g/mol). Both benzene and hexane are non-polar so they will homogeneously mix. The densities of benzene and hexane are 0.8765 g/mL and 0.6594 g/mL, respectively. What is the %(v/v) benzene of the original solution? What is the %(w/v) hexane of the original solution?
