A 5.00-mL aliquot of a solution that contains 3.57 ppm Ni2+ is
treated with an appropriate excess of 2,3-quinoxalinedithiol and
diluted to 50.0 mL. The molar absorptivity of a Ni2+-
2,3-quinoxalinedithiol solution at 510 nm is 5520 L mol-1 cm-1.
What is the absorbance of the above diluted Ni2+-
2,3-quinoxalinedithiol solution at 510 nm in a 2.00-cm cell?
