Answer:
The concentration of the solution,
Explanation:
The absorbance of a solution can be calculated by Beer-Lambert's law as:
Where,
A is the absorbance of the solution
ɛ is the molar absorption coefficient ()
C is the concentration ()
l is the path length of the cell in which sample is taken (cm)
Given,
A = 0.20
ɛ = 27400
l = 1 cm
Applying in the above formula for the calculation of concentration as:
So , concentration is:
