During the equilibrium experiment at room temperature, you prepare the standard solution of FeSCN2 by taking 9.00 mL of 0.1956 M Fe(NO3)3 from the dispenser into a 20 x 150 mm test tube. You pipet 1.00 mL of 0.002028 M KSCN into the same test tube and stir. The absorbance of this solution registers as 0.786 au on the spectrometer. Determine [FeSCN2 ]eq with units M and to 6 decimal places. Input your answer in decimal form.
