Beer Lambert Law Calculator

This Calctown Calculator calculates the Absorbance and Molar absorptivity of a given solution using the Beer-Lambert Law.

I₀(initial intensity)

W/m²

I(final intensity)

W/m²

b(path length)

c(concentration)

mol/dm³

A(absorbance)

ε(absorptivity)

m²/mol

where

A = absorbance

I = intensity of light after passing through the solution

I₀ = intensity of light before passing through the solution

ε = molar absorptivity of the solution

b = path length in m

c = concentration of solution in mol m^-3
