Mass of Sample 1: _.310g Mass of Sample 2: _-2994 Mass of Sample 3: _,3059 Molarity of standardized KMnO4 solution: 004467 1 2 Sample 3 Initial buret reading (mL) 0.25mL 16.50mL 32. 50ml Final buret reading (mL) 16.50mL 32.50mL 48,00 mL Volume of titrant added (mL) 16.20mL 16.00mL 15.some

Calculations 1. The redox reaction occurring during the titration is below. Balance the chemical equation in acidic solution MnOc(aq) + Fe?" (aq) → Mn?"(aq) + Fe''(aq) -> Mnonians + Sterus +8Hugi - Men +SFeraz, & T420 2. Calculate the moles of MnO4- used in each trial. 2 Trial 3. Use the balanced redox reaction from number 1 to determine the moles of Fe2+ in each sample. 3 Trial

4. Calculate the mass of Fe in each sample. 3 Trial 2 3 1 5. Calculate the mass percent of Fe in each sample. 2 2 Trial Mean percent mass Fe: Standard deviation of percent mass Fe.
