Answer:

Using Beer-Lambert Law

Explanation:

The relationship between absorbance #A# and concentration #C# is giving by the Beer-Lambert law:

#A=epsilon xx l xxC#

where, #epsilon# is the molar absorptivity of the solution, #l# is the light path.

Therefore, if you have the absorbance #A#, the concentration can be calculated by: #C=A/(epsilonxxl)#
