The percentage of the amount of cobalt present in the petroleum solution is to be calculated. Concept introduction: The concentration of the cobalt Co (II)-ligand present in the pesticide is given by establishing the relation between the unknown concentration and absorbance to the known concentration absorbance and the volume of the solution. The relationship between the absorbance, molar absorptivity, molar analytical concentration of the solution and the volume of solution is given by. A = ε b c V V t
