67. Solving a chemistry problem

9. When titrating 50 ml of hydrochloric acid with a NaOH solution, the following were obtained
data:
V (NaOH), ml 0 2 4 6 8 10
Electrical conductivity of the solution ω*103 cm 1.50 1.09 0.672 0.633 0.991 1.35
Construct a titration curve in the coordinates ω - V (NaOH). Determine the equivalence point. Calculate the molar concentration of hydrochloric acid. c(NaOH) = 0.01 M
