A chemistry student needs to determine the concentration of iron (III) ions in a water sample using spectrophotometry. The water sample contains an unknown amount of iron (III) ions that need to be quantified with a high degree of accuracy. The student has access to a spectrophotometer and an iron (III) ion standard solution to be used as a reference for the analysis. What is the concentration of iron (III) ions in the water sample?
