If the amino acid moved 6.0 cm on the chromatogram and the solvent front rached 10.0 cm what is the Rf value of the amino acid?

The Rf value (retention factor) is calculated by dividing the distance the amino acid moved by the distance the solvent front moved. In this case, the amino acid moved 6.0 cm and the solvent front reached 10.0 cm. Therefore, the Rf value is 6.0 cm / 10.0 cm = 0.6.
