<h2>Calculate the Rf values</h2>
Explanation:
- In the event that an alternate dissolvable were utilized, the Rf worth would not be the equivalent on the grounds that, contingent upon the dissolvable, there is a distinction in dissolvability. On the off chance that an alternate dissolvable was utilized, the general places of the groups would be different.
- The Rf estimation of the xanthophyll is 66% that of carotene since xanthophyll has a H bond with cellulose, which backs it off, and makes it less dissolvable in the dissolvable. 
- Carotene is progressively dissolvable in 9:1 oil ether CH3)2CO arrangement, which made it be conveyed higher and have a bigger Rf value.
- 
Measure the separation the dissolvable voyaged, which is Df, and measure the separation the test arrangement voyaged, which is Ds. 
- Ascertain the maintenance factor utilizing this condition <em>RF = Ds/Df. </em>
- Basically isolate the separation the arrangement went by the separation the solvent traveled.
