### Experiment: Calibration Curve for FeSCN²⁺ Complex

In this experiment, you will prepare standard solutions to create a calibration curve for the formation of the FeSCN²⁺ complex. This is achieved by reacting different volumes of 0.200 M Fe(NO₃)₃ and 0.002 M NaSCN. All dilutions will be carried out using 0.05 M HNO₃. Using the table provided, calculate the equilibrium concentrations of FeSCN²⁺.

#### Data Table
