3. The UV/Vis allows you to determine the concentration of a colored compound. In the equilibrium experiment, you did a multi-step calculation in order to calculate K for a mixture. Calculate the value of K using the following values (NOTE: you may need to look at the procedure to figure out how to convert from abs to concentration AND pay attention to how concentration changes with total volume) Vol of 0.002 M Vol of 0,002 M Fe(NO Vol water Abs after mixing KSCN 500 ml 2.71 ml 2.29 ml 0.553 Hint: The steps you should follow are 1) Convert abs to conc of FeNCS, 2) determine the equilibrium concentrations of KSCN and Fe(NO 3) calculate K. Step 2 is multiple calculations
