6. Record the volume of KMnO4 dispensed to reach the pink endpoint for each trial. Calculate the moles of KMnO4 dispensed from the burette for each trial, use this to calculate the moles of Fe2+ in your sample. The moles of Fe2+ can be converted to grams and that will give you the % composition by mass of the iron in your O.35g sample.
