Answer:
A = 0.84
Step-by-step explanation:
The absorbance of the myoglobin solution can be calculated by using the Beer-Lambert law:
<u>Where:</u>
<em>A: is the absorbance </em>
<em>ε: is the molar attenuation coefficient = 15,000 M⁻¹cm⁻¹ </em>
<em>l: is the optical path length = 1 cm</em>
<em>C: is the concentration = 1 mg/ml </em>
Since the concentration is given in mg/ml and the molar attenuation coefficient is given in M (mol/L) we need to convert the concentration in mg/ml to mol/L and for that, we need to use the molecular weight of myoglobin = 17.8 kDa = 17.8x10³ g/mol:
Now, we can calculate the absorbance of the myoglobin:
Therefore, the absorbance of the myoglobin solution is 0.84.
I hope it helps you!
