If the concentration of FeSCN in the reference solution is 2.0 x 10^-5 M and the absorbance at this concentration is 0.179M. If the absorbance of a test solution is 0.120 M what will be the concentration of this test solution.

ok this is what i did.

2.0 X 10^-5 M / 0.120 M = 1.66 X10 ^-5 M

what do you guys think ?? i didnt know how to do this.
