Beer-Lambert Law- Definition, Derivation, and Limitations

TīmeklisThe size of the cuvette is 2 cm. Answer: Using Beer-Lambert’s law, we know that. log ( I 0 I) = ϵ l C. where ϵ is the molar absorptivity or the molar absorption coefficient, l is the length of the light path in cm and c is the concentration of the solution. So from the above equation, we have. log I 0 – log I = ϵ l c.
