A standard solution was put through appropriate dilutions to give the concentrations of iron shown below. The iron(II)-1,10,phenanthroline complex was then formed in 25.0·mL aliquots of these solutions, following which each was diluted to 50.0 mL. The following absorbances (1.00-cm cells) were recorded at 510 nm:

(a) Plot a calibration curve from these data.

(b) Use the method of least squares to find an equation relating absorbance and the concentration of iron(II).
