The question is incomplete, here is the complete question:
A murexide soution has a concentration of [tex]3.52\times 10^{-4}M[/tex] and an absorbance of 1.850 and the path length is 1 cm. What is the molar absorptivity of the solution?
Answer: The molar absorptivity coefficient is [tex]5255.7M^{-1}cm^{-1}[/tex]
Explanation:
To calculate the molar absorptivity coefficient, we use the equation given by Beer-Lambert law, which is:
[tex]A=\epsilon Cl[/tex]
where,
A = absorbance = 1.850
[tex]\epsilon[/tex] = molar absorptivity coefficient = ?
C = concentration of the solution = [tex]3.52\times 10^{-4}M[/tex]
l = path length = 1 cm
Putting values in above equation, we get:
[tex]1.850=\epsilon\times 3.52\times 10^{-4}M\times 1cm\\\\\epsilon=\frac{1.850}{3.52\times 10^{-4}\times 1}=5255.7M^{-1}cm^{-1}[/tex]
Hence, the molar absorptivity coefficient is [tex]5255.7M^{-1}cm^{-1}[/tex]
