The answer is zero.
According to below table we can see:
In spectrophotometry, absorbance and transmittance are measurements. Spectrophotometry determines how much radiant energy a substance absorbs at different light wavelengths. The technique is useful for determining the identity of an unknown substance as well as determining the concentration of a substance in a sample using a set of standards.
In the lab or in the field, a transmittance to absorbance table allows for quick conversion of transmittance values to absorbance.
Transmittance Absorbance (AU)
100% 0
99% 0.004
98% 0.009
97% 0.013
96% 0.018
What is absorbance?
- The amount of light absorbed by a solution is measured as absorbance (A), also known as optical density (OD). The amount of light that passes through a solution is measured as transmittance.
- The absorbance has a logarithmic relationship to the transmittance; with an absorbance of 0 corresponding to a transmittance of 100% and an absorbance of 1 corresponding to 10% transmittance.
