5.07-g petroleum specimen was decomposed by wet ashing and subsequently diluted to 500. mL in a volumetric flask. Cobalt was determined by treating 25.00-mL aliquots of this diluted solution as follows: Reagent Volume in mL           Co(II), 3.00 ppm       Ligand     H2O         Absorbance      0.00 20.00 5.00 0.416 5.00 20.00 0.00 0.522   Assume that the /ligand chelate obeys Beer’s law and calculate the percentage of cobalt in the original sample.
