we know Transmittance and absorbance are inversely related, transmittance is the ratio of transmitted intensity to incident light intensity.
Absorbance A = 2 - log ( % T ) .-----(1)
if % transmittance is known.
absorbance A = 2 - log ( 25.8 )
since logrithm of 25.8 = 1.4116 , puting in equation (1) we get
Absorbance A = 2 - 1.4116 = 0.5883 Answer.

A student need to prepare four standard solutions by serially diluting a stock solution with concentration 5.0 times 10^-4 N. Standard I will be created by transferring 5.00 mL of the stock solution to the mark with deionized water. The remaining standard solutions (Standards 2 - 4) will be created by transferring 25.00 mL of the previously made standard solution to a 50.00 mL volumetric flask, then...

If you use a Spec-20 with an analog scale you must read percent transmittance, and convert your transmittance reading to absorbance. What is the absorbance of a solution that transmits 100% of the light shining on it? What is the absorbance of a solution that transmits 5.0% of the light? What is the absorbance of a solution that transmits 0% of the light shining on it?
