What Is The Concentration?

Dichromate ion, Cr2O7^2-, reacts with aqueous iron(III) ion in acidic solution according to the balanced equation

Cr2O7^2-(aq)+Fe^2+(aq)+14H^+(aq)—->2Cr^3+(aq)+6Fe^3+(aq)+7H20(l)
 
What is the concentration of Fe^2+ if 46.99mL of .2004M K2Cr2O7 is needed to titrate 
50.00mL of the Fe^2+ solution?

  1. .04699L(.2004M/L)(6molFe/1molCr2O7) = .0565molFe
    .0565molfe/.05L = 1.13M
