An aqueous solution of hemoglobin has a molar absorptivity value of 18...
Given parameters:
Molar absorptivity value (ε) = 18,600 L mol^-1 cm^-1
Absorbance (A) = 0.1
Wavelength (λ) = 540 nm
Cell thickness (b) = 1 cm
We can use the Beer-Lambert law to calculate the concentration (c) of the hemoglobin solution.
Beer-Lambert law states that the absorbance (A) of a solution is directly proportional to the concentration (c) and the path length (b) of the solution:
A = εbc
Rearranging this formula, we get:
c = A/ (εb)
Substituting the given values, we get:
c = 0.1 / (18,600 L mol^-1 cm^-1 x 1 cm)
c = 0.00000537 mol/L
Converting the units to M, we get:
c = 5.37 x 10^-6 M
Therefore, the concentration of the hemoglobin solution is 5.37 x 10^-6 M, which is equivalent to option B.
