C)L/(mol .cm)
D)mol/L

Question

​The unit for molar absorptivity is:
A)​L/cm
B)​(L .mol)/cm
C)​L/(mol .cm)
D)​mol/L

Quizplus · Accepted Answer

The unit for molar absorptivity is L/(mol.cm), which represents the extent to which a substance absorbs light at a particular wavelength. This unit is obtained by dividing the extinction coefficient (L/mol.cm) by the molecular weight of the substance (mol/L). Choice A and B are incorrect because they do not have the mol term in their units. Choice D is incorrect because it represents the concentration of a solution, not the molar absorptivity of a substance.
