1. When measuring the electrical conductivity of aqueous solutions of CaCl2 with different concentrations of the substance, the following data were obtained:
w (CaCl2) % 0.5 2.5 5 7.5 10
χ, S/m 7.00 2.92 1.80 1.28 0.94

Draw a graph and find the normal concentration of the analyzed CaCl2 solution if its specific electrical conductivity is χ = 2.00 S/m.
