Astudent measures the absorbance of a sample of red dye #3 using a spectrophotometer. if the absorbance is measured as 0.468, what is the concentration of red dye #3 in the sample?
enter your answer in units of micromolar to three significant figures.
n the lab spectrophotometer, d = 1.00 cm. for red dye #3, ε = 7.96 x 104 m-1 cm-1.

5.88 μM is the concentration of red dye in the sample.

Explanation:

Absorbance is defined s capacity of a substance to absorb a light of a specified wavelength.It is calculated by using Beer-Lambert Law:

A = absorbance

= Molar absorptivity

c = concentration

l =  Length of the solution through which light passes

Given, A = 0.468, l = d = 1.00 cm,c = ?

()

5.88 μM is the concentration of red dye in the sample.
