We did a lab in chem involving Fe(SCN-) and using Beer's law and absorbency to find the equilibrium constant.
For the data we have .0025 M Fe(NO3)3 in .1M HNO3, .0025 M KSCN- in .5M KSCN, and .1M HNO3 (the stock solutions).

1. Make a working solution from the stock 0.0025 M Fe(NO3)3 by diluting 4.0 mL to exactly 100.00 mL.

And much more important:
The data I have gives the following info:
Fe3+ (mL): .1.0
KSCN (mL): .5.0
HNO3 (mL): 4.0
ttl vol:(mL): 10.0
Absorb.: .1
[Fe(SCN)]:

How do you find the concentration of Fe(SCN)?
Thanks!!!

Did the lab involve measuring the absorbance of several standards and plotting the data to get the equation for Beer's Law? If it did, the equation of the best fit line for the data should be in the same form as Beer's Law A=abc.
