<u>Given:</u>
Distance of solvent front = 68 mm
Distance of unknown = 48 mm
<u>To determine:</u>
The rf value
<u>Explanation:</u>
The retention factor or the rf value is given by the ratio of distance traveled by the unknown to the distance traveled by the solvent front
RF = distance by unknown/distance by solvent
RF = 48/68 = 0.706
Ans: the RF value is 0.706
