318. To determine the concentration of KI in alcohol, the dependence of resistance on the content of potassium iodide in alcohol is used:
CKI, mg/25 ml 0.52 1.04 1.78 2.41 3.35
R, Ohm 7.20 3.64 2.15 1.59 1.16
Construct a calibration curve W - C from these data and use it to determine the molar concentration of the equivalent of potassium iodide if the resistance of this solution is 3.10 ohms.
