The transmittance of a solution, containing 7.3 mg of potassium dichromate per 100 cm³, taken in a cuvette of path length of 1 cm is measured at 455 nm. If the percentage transmittance found to be 6, calculate the molar absorptivity of the oxidizing agent.

The relationship between transmittance, absorbance, and molar absorptivity in spectroscopic methods is governed by the Beer-Lambert law:

\[
A = \epsilon \cdot c \cdot l
\]

Where:
- \(A\) is the absorbance,
- \(\epsilon\) is the molar absorptivity (also called molar absorption coefficient),
- \(c\) is the concentration of the solute in mol/L,
- \(l\) is the path length of the __________ ___ _______ ____ _______ ______ ____ ______ _________ _____ _____.
