[CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
|
Molar extiction coefficient can be determined by formula (A-absorbance, -molar extinction coefficient, C-concentration, L-pathlength)
|
|
A = * C * L
|
|
|
= A * C * L
|
|
|
= (A * C) / L
|
|
|
= A / (C * L)
|
Explanation:
Detailed explanation-1: -The measure of how strongly a substance absorbs light at a particular wavelength, and is usually represented by the unit M-1cm-1 or L mol-1cm-1.
Detailed explanation-2: -Molar absorptivity Decadic absorbance divided by the path-length l and mole concentration c, of the absorbing material. = A10 / cl. The molar absorptivity is a Beer-Lambert absorption coefficient.
