Can someone please help me solve this prelab question? The third one
A student attempts to separate a sample of cyclohexane and ethylbenzene by distillation. After the distillation the student obtains an n20D of 1.4355 for what should be pure cyclohexane with a volume of 23.5 mL. Did the student obtain pure cyclohexane? If not, what volume of ethylbenzene is present in the distilled cyclohexane?
Pre-Lab Questions; Draw a schematic of the setup that you will use for the simple distillation. Be sure to indicate all of the clamp and clip locations. 2. How would you correct for temperature if your refractive index reading was taken at 22 degree C as opposed to 20 degree C? 3.
