Presume a student used 1.0mL of 2-methylcyclohexanol and 2mL of phosphoric acid in a dehydration reaction.  After purification of the reaction product, 0.484 g of a mixture of alkenes was isolated.  Explain what is the percentage yield of the dehydration?  If the density of 2-methylcyclohexanol is 0.930 g/mL. If problems are encountered refer to the section of useful calculations
