Question

Calculate the amount of cyclohexanone (in grams) that would be synthesized from 19.64 ml of cyclohexanol. Hint: Use the density of the cyclohexanone and the molar masses to calculate. (Put your answer in 3 significant figures.)

Answer 1

Density of cyclohexanol = 0.9624 g/mL

So the mass of 19.64 mL = 19.64 x 0.9624 = 18.9 g

Molar mass = 100.158 g/mol

So number of moles = 18.9 / 100.158 = 0.189 moles

The number of moles of cyclohexanone formed = 0.189 moles

Mass in grams = 0.189 x 98.15

= 18.5 grams
