I am having a difficult time understanding this problem,can someone please assist? Thank You!
4. In order to analyze a commercial hydrogen peroxide solutio n by the procedure described in this experiment, you must first dilute the commercial peroxide solution with distilled water. For example, 10 mL of a commercial peroxide solution measured with a volumetric pipet was diluted to 100 mL in a volumetric flask and mixed thoroughly. 25.00 mL of the diluted peroxide was titrated. Assume th the diluted peroxide solution had a density of 1.000 g mL 25.00 volume of diluted hydrogen peroxide solution, mL molarity of the potassium permanganate solution, M potassium permanganate solution 1.992 x 10-2 initial buret reading, mL final buret reading, mL 1.17 26.09 (1) Calculate the number of moles of KMnO4 (2) Calculate the number of moles of H2O2 answer (3) Calculate the mass of H202 in the unknown. (4) Calculate the percent H202 in the diluted peroxide. (5) Calculate the percent H,02 in the commercial hydrogen peroxide. Show transcribed image text
