A solid sample which is having some Fe2+ ion weighs 1.062g. It requires the 24.12 mL 0.01562 M KMnO4 to titrate the Fe2+ in the dissolved sample to a pink endpoint.
1. Determine the numbers of moles MnO4 - ions are required?
2. Calculate the numbers of moles Fe2+ are there in the sample?
3. Determine the numbers of grams of iron are there in the sample?
4. Calculate the percentage of Fe in the sample?
