A red spot is measured 23mm away from the original sample spot, a blue spot is 42mm away, and a yellow spot is 49mm away. The distance from the original spot to where the solvent stopped is 55mm. a) Calculate the Rf value for each component in the mixture. (Show your work and report the correct number of significant figures.) in reel spot Rf=5523=0.418180.42 as. ( in yeltow spot 49/55=0.890909 b) The silica gel plate is polar. Rank the three components in the mixture from lowest to highest polarity. Explain your
