- It can simply obtained by multiplying the absorption coefficient by the molecular weight. Thus, ϵ = 0.0376 x 100 = 3.76 L·mol -1 ·cm -1 The Importance of Concentration The proportion of the light absorbed will depend on how many molecules it interacts with. Suppose you have got a strongly colored organic dye.
