A sample of ferrous ammonium sulfate hexahydrate, FeSO4·7H2O, weighing 3.55 g is dissolved and diluted to 250.0 mL. From this solution, 20.0 mL is taken and titrated with KMnO4 solution in acidic medium. The reaction is: \(\mathrm{MnO_4^- + 5Fe^{2+} + 8H^+ \rightarrow Mn^{2+} + 5Fe^{3+} + 4H_2O}\). If 18.2 mL of the KMnO4 solution is required for the titration, calculate the concentration of the KMnO4 solution in mol·L⁻¹.
