After completing trial E3 of the experiment, a student uses her calibration curve to find that the equilibrium concentration of the product is 1.12x10-4 M. If the "initial" concentrations of Fe3+ and SCN in the reaction mixture are those given below, what is the equilibrium concentration of Fe3+, [Fe3+leg? Give your answer in millimolar (mM) to three decimal places.

Question

I need help with this problem 

After completing trial E3 of the experiment, a student uses her calibration curve to
find that the equilibrium concentration of the product is 1.12x10-4 M. If the "initial"
concentrations of Fe3t and SCN in the reaction mixture are those given below,
what is the equilibrium concentration of Fe3+, [Fe3+leg? Give your answer in
millimolar (mM to three decimal places.
[SCN ]o= 6.11x10-4 M
[Fe*]o = 1.01x10-3 M
[FENCS2+]eg = 1.12x10-4 M
