Molar concentration of the dye stock solution: 2.52e-5 mol/L
Operating Wavelength: 630 nm
| Solutions (Dilutions) |
Absorbance (A) (a.u.) |
|---|---|
| 1 | 0.073 |
| 2 | 0.118 |
| 3 | 0.258 |
| 4 | 0.477 |
Using linear regression determine the absorbance/concentration relationship for the dye.
[dye] =_____ x A
The average value of absorbance = (0.073+0.118+0.258+0.477)/4 = 0.2315M.
Given that [dye] = 2.52×10-5 mol/L = 2.52×10...
