7.  A chrоmаtоgrаphy experiment wаs used tо determine components in a mixture. a.  Calculate the Rf values for spot A and spot B using your ruler. Show your work. Use appropriate significant figures in your measurements and calculations.  (6 points, WCSP25.[x])    b. The stationary phase for the previous chromatogram was cellulose, which is highly polar due to the presence of multiple hydroxyl (OH) groups.  The mobile phase was water.  Given this, identify which amino acid (a building block for proteins) shown below corresponds to spot A and B.  Explain your reasoning. (6 points)   Enter the Rf value of spot A in the box below.
