Homework Help: Chemistry

Posted by Renee on Sunday, April 13, 2008 at 10:23pm.

A standard solution of FeSCN2+ is prepared by combining 9.00 mL of 0.200 M Fe(NO3)3 w/1.00 mL of 0.0020 M KSCN. The equilibrium concentration of FeSCN2+ ([FeSCN2+]std) for this standard solution is assumed to be ____ M.

I tried this problem by adding the moles of Fe(NO3)3 and KSCN and dividing that by 0.01 L. I got 0.1802 but it's wrong.
