4.A student finds the %T of a 2.0 x 10-3M solution of Congo Red solution to be 35 % when measured in a 1.0-cm cuvet at a wavelength of 410 nm. What is the absorbance of this solution?
We will calculate the absorbance by using following equation,
Absorbance = log ( 100 / %T)
Here, log of 100 = 2.
Therefore,
Absorbance = 2 - log %T
= 2 - log 35 %
= 2 - 1.544
= 0.456
Therefore absorbance is 0.456.
