Molar absorptivity

Explanation:

@zeddmaan☺️

Answer 2

Solution:

Option d is correct answer.

Explanation:

Molar absorptivity is defined as the absorbance of a medium having concentration 1 mol/dm3 and thickness 1cm. Hence, absorbance divided by the path-length l and mole concentration c, of the absorbing material.

ε = A / cl.

The molar absorptivity is a Beer-Lambert absorption coefficient.
