A student performs a separation by TLC on a silica gel platee that results in three spots. A red spot is measured 23 mm away from the original sample spot, a blue spot is 42 mm away, and a yellow spot is 49 mm away. the distance from the original spot to where the solvent stopped is 55 mm. a) calculate the Rf value for each componenet in the mixture (show work and report th correct number of significant figures) b) the silica gel plate is polar. rank the three componenets in the mixture from lowest to highest polarity. Explain your answer.
