Homework Help: Chemistry DrBob

You told me the steps on a previous post but i must have forgot how to work out absorbance or ICE cus i keep getting the wrong answer
...
The standard solution of FeSCN2+ (prepared by combining 9.00 mL of 0.200 M Fe(NO3)3 w/1.00 mL of 0.0020 M KSCN) has an absorbance of 0.520.

If a trial's absorbance is measured to be 0.275 and its initial concentration of SCN– was 0.00060 M, what is the equilibrium concentration of SCN–?

Show your calculation for a in the standard.
Show your calculation for c in the unknown. then we can talk about ICE.
