A chemistry student wants to determine the concentration of a solution containing iron (III) ions. Using colorimetry, they measure the absorbance of the solution at a specific wavelength and plot a calibration curve with solutions of known iron (III) ion concentration. The student then measures the absorbance of their unknown solution at the same wavelength and uses the calibration curve to determine the concentration of iron (III) ions in the sample. What is the concentration of iron (III) ions in the unknown solution, in units of moles per liter?
