Need help with chromatogram work

Postby pre_vet_gal » Wed Feb 23, 2005 3:24 am

I have a lab question that I am unable to figure out. If someone could help I would be greatful! :D

Calculate the R_f of pigment that moved 7cm on a chromatogram that had a 13.6-cm front.

Thanks !

Rf= Distance moved by the pigment / Distance moved by solvent front
