54. Solving a chemistry problem

65. During chromatography of a substance in a thin layer, one spot was found on the chromatogram at a distance of 47 mm from the start line and 3 mm in diameter. In this case, the solvent traveled a distance of 10.0 cm. Draw a view of the chromatogram and calculate the retention factor for the analyte, the number of theoretical plates N and the height equivalent to the theoretical plate H.
