Question

Could you please help me with calculating the initial concentrations, and please tell me if I did table 4 correctly. I would like to see one or two calculations for the second bullet so I can figure out how to do them all. Thank you!
13. Use a 3.00 mL pipette to deliver 0.0020 M Fe(NO3)3 solution and burettes to deliver the required volumes of KSCN solution and DI water into clean and dry test tubes. Note that this set of combinations uses the more dilute Fe(NO3)3 solution 0.002M). Stir each solution with a glass stir rod to mix the reagents.

Measure the % transmittance of each equilibrium solution following the same steps as in Part I, steps 3 through 7. NOTE: You are not making a graph this time. Simply record the % transmittance values in your data table for further analysis. 15. Rinse the cuvettes with tap water followed by distilled water 3 times and place in the used clean cuvette bin. 16. Dispose of your equilibrium solutions into the waste container provided, clean the test tubes with soap and water, rinse twice with tap water and twice with distilled water.
