Explanation:
Percent transmittance and absorbance are related to each other by a logarithmic function. The relationship between absorbance and percent transmittance is given by the Beer-Lambert law:
A = log(Io/I)
where A is the absorbance, Io is the intensity of light incident on the sample, and I is the intensity of light transmitted through the sample.
Percent transmittance is defined as the ratio of the intensity of light transmitted through the sample to the intensity of light incident on the sample, expressed as a percentage:
%T = (I/Io) x 100
By rearranging the Beer-Lambert law, we can express percent transmittance in terms of absorbance:
%T = 10^(-A) x 100
Therefore, if the absorbance of a solution is 1.0, then the percent transmittance is:
%T = 10^(-1) x 100 = 10
This means that only 10% of the incident light is transmitted through the solution, while 90% of the incident light is absorbed by the solution.
