D. No unit
Answer:A
What is the unit of molar absorptivity or absorptivity which is used to determine absorbance A in Beer Lambert’s formula?
A. L mol-1 cm-1 B. L gm-1 cm-1 C. Cm D. No unit
Explanation: The unit of absorptivity is L mol-1 cm-1. If the concentration is represented as gm per litre it becomes L gm-1 cm-1.
