Asked by UCI student

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 0.510. If a trial's absorbance is measured to be 0.250 and its initial concentration of SCN− was 0.00050 M, the equilibrium concentration of SCN− will be...



ive tried for a while, but i keep on not getting the correct answer.

you don't need to just give it to me, but could someone show me the steps and reasoning needed to get the proper answer?
