Answer the following two questions A paper chromatography experiment was conducted on a mixture of amino acids including Aspartic acid (Asp), Glutamic acid (Glu), Histidine (His), Leucine (Leu), Phenylalanine (Phe) and Proline (Pro). The following Rf values were determined: Asp (0.245), Glutamic (0.275), His (0.295), Leu (0.745), Phe (0.685) and Pro (0.445). In the experiment, a colored spot for unknown amino acid "W" was found centered at a distance 25 mm from the start line when the solvent line had...
