what would be the absorbance of a solution having a transmittance of 1.500%

The absorbance AAA of a solution having a transmittance TTT (in percent) of 10% can be calculated using the formula:

A=2−log⁡10(T)A=2-\log_{10}(T)A=2−log10​(T)

Substituting T=10%T=10%T=10%:

A=2−log⁡10(10)=2−1=1A=2-\log_{10}(10)=2-1=1A=2−log10​(10)=2−1=1

So, the absorbance of the solution is 1. This means the solution absorbs light such that only 10% of the light passes through it. Absorbance and transmittance have an inverse logarithmic relationship, where low transmittance corresponds to high absorbance and vice versa.
