Chemistry Equilibrium Constant PLEASE Help!?

In an experiment, equal volumes of 0.00150 M FeCl3 and 0.00150 M NaSCN were mixed together and reacted according to the equation:
Fe3+ (aq) + SCN– (aq) <--> Fe(SCN)2+ (aq)
The equilibrium concentration of FeSCN 2+(aq) was 2.70*10^-4
Calculate the equilibrium constant for this reaction.
