Asolution has a concentration of dye= 0.0003 m at a given time during the reaction. the sample described has a ln(a0) = -4.1655. assuming the path length is 1 cm what is the molar absorptivity constant for the dye? report answer to two decimal places. no units required.

is the molar absorptivity constant for the dye.

Explanation:

Using Beer-Lambert's law :

where,

A = absorbance of solution

C = concentration of solution =

= Molar absorptivity constant

l = path length

Given : C = 0.0003 M , l = 1 cm

is the molar absorptivity constant for the dye.
