To determine the concentration of a dye in a shampoo, a student measure the absorbance of suitably prepared samples of known concentrations of the dye. The plot below is a calibration plot of the student's data. Absorbance at 450 nm, A 1 0.8 0.6 0.4 0.2 Concentration vs Abs of Dye 0.02 0.04 0.06 0.08 Concentration, mol L-1 i. As the concentration of the dye increases, the absorbance at 450 nm [Select] ii. Three unknown samples were measured. Using the calibration plot above, estimate the concentrations of the dye in the three samples. Sample Absorbance Estimated Concentration [Select] mol 1 0.418 L-1 [Select] mol 2 0.550 L-1 [Select] mol 3 0.115 iii. Which sample is the most concentrated sample of dye? Sample 2 iv. Which sample is the most dilute sample of dye? Sample 3
