Chemical Thinking P2S1 In-Lab Report v1.1 | Project 2 Session 1 In-Lab Report All work must be well-written and organized . If your penmanship is poor, you must type all responses. If you need to organize your thoughts, please use a separate sheet of paper. A major objective of this lab course is to develop skills in scientific communication. Just having the right “answer” is not good enough – you must communicate clearly and succinctly and use terms and concepts correctly . When typing, all sections must have a line spacing of 1.5 to give room for TA feedback (the document is set to this spacing). R f Calculation (6 p) State the equation that gives the retention factor R f . Next, give one example calculation in which actual values are plugged in and the results are shown. Be absolutely certain all sig figs and units are correct. Here you are putting into further practice the appropriate presentation of scientific calculations. The equation used in order to find the retention factor (R f ) is: R f = Distance traveled by the solute (cm)/ Distance traveled by the solvent (cm) Example calculation (From data gathered in lab) R f = 0(cm)/4.7(cm) R f = 0.0 Results (10 p) With the “center of mass” for each spot indicated, attach your paper chromatograms (or paste in photos/scans).

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
