70. Solving a chemistry problem

6. Weighed portion of the drug Paracetamol weighing 0.1997g. placed in a 50 ml flask and made up to the mark with titration solution. Then 10 ml of the resulting solution was transferred into a 50 ml volumetric flask, brought to the mark with a titration solution and titrated with 0.1 M KOH in isopropyl alcohol. 2.578 ml of KOH in isopropyl alcohol 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 151.17)
