Question

How do you calculate grams of H2O2 from the expeimental data given?

(acidic medium) MnO4 + H2O2 = Mn2+ + O2 The spectator ion, K, has been left out of the equation. CH" + 2 MnO4 + Shooa 2M na +502 + 8 H2O BRAND OF HYDROGEN PEROXIDE ANALYZED: If no brand name is provide, create a name for the hydrogen peroxide brand. Be creative. AVERAGE EXPERIMENTAL MOLARITY OF THE KMnO4 SOLUTION USED: 0.0968 M KMnO4 ERLENMEYER FLASK NUMBER: #4 #1 #2 #3 USE A 5.00 mL VOLUMETRIC PIPETTE TO MEASURE THIS VOLUME OUT! H2O2 DATA Aliquot size used 5.00 mL H2O2 5.00 mL H2O2 5.00 mL H2O2 5.00 mL H2O KMnO4 DATA Final KMnO4 burette reading 19.21 mL 36.40 mL 19.24 mL mL Initial KMnO4 burette reading 0.00 18.21 0.00 mL mL mL mL Total Volume of KMnO4 used 18.21 ml 18.19 mL 18.24 mL mL Grams of H2O2 in original 5.00 mL sample g g 9 H2O2 H2O2 H2O2 H2O2 Using your experimental data and the stoichiometric relationship between the two reactants, MnO.', and H2O2, calculate the number of grams of hydrogen peroxide in each sample.
