Determination of iron by redox titration

[brittni8924]

If a 2.893 g sample of an unknown containing iron requires 28.45 mL of the permanganate solution described in Pre-Laboratory question 3 to reach the endpoint what is the % Fe in the unknown?

Start with the reaction equation.

The problem statement is missing some information.

 

[Borek]

I suppose the missing information was listed in the question 3.

Still, reaction equation is a starting point.

brittni8924,
What if you were to first write the balanced reaction, and then solve (or let one of us solve) the problem purely symbolically; then, you would clearly see what information is missing (but we are not encouraged to solve problems in this board until the original poster puts in and shows enough effort).
