Given data, k for blue dye = 600.4 M-1 Absorbance (A) = 0.204 Beer's Lambert Law : According to Beer's Lambert Law absorbance is directly proportional to concentrate and path length of solution. A = ε.C.l Where, A = absorbance C = concentration l = length A = ε.C.l A = k.C Where, { k = ε.l } 0.204 = 600.4 M-1×C C = 0.204/600.4M-1 C = 0.0003398 M C = 3.398×10-4 M Ans, Molarity = 3.398×10-4 M
