The Re value is used to help identify substances that are separated by paper chroma- tography. It is calculated with the following equation, where Ramino acid is the distance travelled by the amino acid in centimeters and Rsolvent is the distance travelled by the solvent in centimeters. Calculate the Rę if an amino acid travels 2.0 cm and the solvent travels 6.5 cm.
