Given:
Distance of solvent front = 68 mm
Distance of unknown = 48 mm
To determine:
The rf value
Explanation:
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
