I need to plot the observed emf in mV vs logarithm of ppm F to obtain a calibration curve. From a prepared stock solution of 100 mL and the KCl molarity is 0.1M for it. From dilution of this solution, a 20 ppm, 10ppm, 5ppm, 2.5ppm, and 1.25 ppm were made. Im not sure how to go about setting this up.
