could anyone help me with this question

I Some solid ammonium iron(ii) suiphate, FeSO, (NH,),SO,.6H,O, was made up to 500 cm of solution using difute sulphuric acid. 25.00 cm' of the solution was pipetted into a conical flask. 22.80 cm' of a 0.020 mol dm3 solution of potassium manganate(vII) was needed for a complete reaction. Calculate (in mol dm ) the concentration of the ammonium iron(ii) sulphate solution.

FeSO, (NH,),SO,.6H,O ??

Can you write the two half-equations and hence the overall equation for the oxidation of Fe2+ (do you know what it oxidises to?) and for the reduction of acidified manganate(VII) (do you know what it reduced to?)?
