6. Bend the chromatography paper over a
pencil supported by the beaker and tape it
so that the paper just dips into the
solvent.
7. Do not move the jar and allow the solvent to
flow up the chromatography
paper until it
is
almost up to the pencil.
8. Remove the paper from the solvent and
mark the solvent front (
the farthest it has
traveled) with a pencil
. Staple/tape the
chromatography paper
to your lab here:
Rf value-distance traveled by the pigment
distance traveled by the solvent

11. Find each of the pigments on your paper.
Carotenes are yellow or orange pigments
that travel the farthest. Lutein is a gray
pigment just below the carotenes and may
be difficult to see. Chlorophyll a travels
the next farthest and is a blue-green
pigment. Yellow pigmented xanthophylls
and yellow-green chlorophyll b are found
just below the chlorophyll A.
2. With your metric ruler, complete the table
below and calculate the Rf value

Not sure if I measured the distance right in metric also please calculate Rf value the equation is distance traveled by the pigment over distance travelled by the solvent
