How is the retention factor (R_f) value calculated?
Distance traveled by the solvent / Distance traveled by the solute
Distance traveled by the solute / Distance traveled by the solvent
Concentration of the solute / Concentration of the solvent
Mass of the solute / Mass of the solvent
Explanation
The R_f value is calculated as the distance traveled by the solute divided by the distance traveled by the solvent.
