Answer:
The percentage deviation is %
Explanation:
From the question we are told that
The concentration is of the solution is
The true absorbance A = 0.7526
The percentage of transmittance due to stray light %
Generally Absorbance is mathematically represented as
Where T is the percentage of true transmittance
Substituting value
%
The Apparent absorbance is mathematically represented
Substituting values
= 0.7385
The percentage by which apparent absorbance deviates from known absorbance is mathematically evaluated as
%
Since Absorbance varies directly with concentration the percentage deviation of the apparent concentration from know concentration is
%
