Asked Nov 6, 2019

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

check_circleExpert Solution
Step 1

The average value of absorbance = (0.073+0.118+0.258+0.477)/4 = 0.2315M.

Step 2

Given that [dye] = 2.52×10-5 mol/L = 2.52×10...
