Hey there!:
Density of cyclohexanol = 962Kg/m³ = 962*0.001g/cm³ =0.962g/ml
mass = density *volume= 0.962*20 = 19.24grams
% yield =
Number of moles of product produced *100 / ( number of moles of reactant taken)
moles of cyclohexanol = 19.24/100.158 = 0.192moles
moles of moles of cyclohexene = 12/82.143 = 0.146 moles
% yield = 0.146*100/0.192 = 76.04%
Hope that helps!
