An analytical chemist uses thin-layer chromatography (TLC) to monitor the progress of a synthetic reaction. The resulting chromatogram, alongside a metric scale, is shown below.

TLC Chromatogram

Calculate the Rf R_f\,Rf​ value for substance Q.

Use the equation:

Rf=distance moved by substancedistance moved by solventR_f = \frac{\text{distance moved by substance}}{\text{distance moved by solvent}}Rf​=distance moved by solventdistance moved by substance​
