Given in the question - 1 mole of cyclohexanol = > 1 mole of cyclohexene Molar mass 100.16 g/mol moles of cyclohexanol =.240 / 100.16 = 0.002396 moles Molar mass 82.143 g/mol moles of cyclohexene formed @100 % yield = 0.002396 Molar mass 82.143 g/mol mass of cyclohexene @ 100 % =.002396 x 82.143 = 0.197g bur we have. 138g so % yield =.138 /.197 = 70.0 % Ans - 70 percentage yield of cyclohexene.
