40. The dependence of the electrical conductivity of a KCl solution on concentration is expressed as follows:
Cn, mol/l 0.004 0.008 0.012 0.016 0.020
æ, Sm•m–1 0.05769 0.1137 0.1687 0.2230 0.2767
The resistance of the cell filled with the analyzed KCl solution is 442.6 Ohm. The distance between the electrodes is 0.0075 m, their area is 1.2 • 10–4 m2. Determine the concentration (g/l) of the potassium chloride solution.
