What is the concentration of Cr2O7 in mol/L?
The potassium dichromate solution is first standardized by titration with 20.00 mL of an acidified 0.06 mol/L solution of the primary standard, iron(II) ammonium sulfate-6-water. The standardized dichromate solution is then titrated against a sample of the acidified tin(II) chloride solution.
TITRATION OF IRON(lI) SOLUTION
(volume of K2Cr2O7(aq) required to react with 20.00 ml of 0.06 mol/L Fe2+(aq))
Trial; ( 1 ) { 2 } [ 3 ] | 4|
Final vol: (13.8) {24.4} [35.2] |45.9|
Initial vol: (2.3) {13.8 } [24.4 ] |35.2|
(that is the titration table)

Well, we can give you the redox equations, and establish the stoichiometric equivalence..
Explanation:
The iron(II) salt is OXIDIZED....
Dichromate ion,
And overall...
The standardized dichromate solution is then reacted with stannous ion...
Anyway you have the data....
