26. In a certain paper chromatography experiment, the Ri values of components X, Y, and Z are 0.25, 0.50, and 0.75. If the spot of component Z traveled 72 mm, the solvent front 26. would have traveled А. 18 mm В. 24 mm C. 54 mm D. 96 mm E. 216 mm
Paper Chromatography Calculate the Rf for a spot that travels 2.41 cm from the baseline while the solvent travels 7.85 cm from the baseline. Answer with the number; there are no units for Rf I got the answer: 0.3070063694267516 2.41/7.85 = 0.3070063694267516 just wanted to make sure.

Explain why the dye spots are elongated and not round on your chromatogram.
You run the chromatography system with paper as the stationary phase and 70% isopropanol as the mobile phase. You determine the Rf of a polar analyte to be 0.40. If you use 100% isopropanol (a less polar solvent) instead of isopropanol as the mobile phase what would you expect to happen to the Rf value? No value effect on Rf higher lower could be higher or lower
