Since Rf values are calculated as such:
The Rf value for the first slip is 2.9/9.9= 0.292(to 3sf)
With the Rf values, we can match 2 substances to see if they are the same (:

Chromatography
Here are the results for my chromatography. The colours aren't really visible so I marked an "x" in the middle of the colour stain. For one of the chromatography slips the solvent front was marked when the it was removed from the water but for some reason the blue colour was above the solvent front O: So I shall only calculate the Rf value of the first slip although the other one has more obvious colours.

The Rf value for the first slip is 2.9/9.9= 0.292(to 3sf)
