Homework Help: Chemistry

What is the molarity of this dichromate solution?
A potassium dichromate solution of an unknown molarity was used to titrate a solution of FeSO4 prepared by dissolving a 0.350g of pure iron wire in H2SO4 and reducing the FE3+ produced to FE2+. 36.24 mL of the dichromate solution was required to reach an end point. What is the molarity if the dichromate solution?


I THOUGHT I knew how to find unknown molarities, but this whole "reducing the Fe3+ to Fe2+" thing is confusing me.
