86. Solving a chemistry problem

30. A sample of the drug Sodium benzoate weighing 0.1995 was placed in a 25 ml flask and brought to the mark with a titration solution. Then 15 ml of the resulting solution was transferred into a 50 ml volumetric flask, brought to the mark with titration solution and titrated with 0.1 M HCl. 8.104 ml of HCl was used for titration. Write a diagram of the quantification process, indicate the indicator, fix the equivalence point. Calculate the titer and content of the active substance in the sample. (The molecular weight of the analyte is 144.11).
