A = ε l c. (a) Define the terms in the formula: A = ε l c. (Pick your answers using the letter of the correct definition.)

A. pathlength of light through the cell
B. concentration, in mol/L, of the stock solution from which the sample was made
C. absorbance measured by the spectrometer
D. molar absorptivity, a constant unique to that substance at that wavelength
E. the wavelength of the light being used for the measurement
F. concentration, in mol/L, of the sample solution being measured definition of l definition of c definition of ε definition of A

Explanation:

Using Beer-Lambert's law :

Formula used :

[tex]A=\epsilon \times c\times l[/tex]

where,

A = absorbance of solution

c = concentration of solution

l = length of the cell

[tex]\epsilon[/tex] = molar absorptivity of this solution

According to question:

A = (C) : absorbance measured by the spectrometer

c = (B) : concentration, in mol/L, of the stock solution from which the sample was made

l = (A): pathlength of light through the cell

ε =  (D) : molar absorptivity, a constant unique to that substance at that wavelength
