82. When titrating 50.0 ml of a mixture of NaOH and NH4OH with a solution of HCl with a concentration of 0.1 mol / l, the following data for problem numbers were obtained - table 23 (electrical conductivity χ • 103 cm). Plot the titration curve and calculate the concentration (g / L) of NaOH and NH3 in the test solution.
