Question

The percentage transmittance
of an aqueous solution of unknown compound is 20% at 25º C and 300
nm for a 2 x 10
-5 M solution in a 4 cm cell. Calculate the absorbance and

Answer 1

Answer:

Here is an example of directly using the Beer's Law Equation (Absorbance = e L c) when you were given the molar absorptivity constant (or molar extinction coefficient). In this equation, e is the molar extinction coefficient. L is the path length of the cell holder. c is the concentration of the solution.
