the claim

The retention factor (Rf) value in paper chromatography is calculated by dividing the distance traveled by the solute by the distance traveled by the solvent front.

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that the retention factor (Rf) value in paper chromatography is calculated by dividing the distance traveled by the solute by the distance traveled by the solvent front?

Yes. Multiple authoritative sources and reference materials confirm that the retention factor (Rf) in chromatography is calculated by dividing the distance traveled by the solute by the distance traveled by the solvent front.
