A solid sample containing some Fe2+ ion weighs 1.750 g. it requires 36.44 ml 0.0244 M KMnO4 to titrate the Fe2+ in the dissolved sample to a pink end point.

There is no question... :confused:

But if I guess right...

1. Write down the balanced equation for the reaction taking place between KMnO4 and Fe^2+.
2. Find the number of moles of MnO4^- used.
3. Find the number of moles of Fe^2+ that should be in the sample.
4. Find the mass of the Fe^2+ in the sample.
5. Find the percentage of Fe^2+ in the sample by using the masses that you have.
