How Do You Convert Transmittance to Absorbance?

AI Thread Summary
To convert transmittance to absorbance, use the formula A = -log(T), where A is absorbance and T is transmittance expressed as a decimal. For a transmittance of 58.8%, first convert it to decimal form (0.588). Applying the formula, absorbance is calculated as A = -log(0.588), which equals approximately 0.232. It's important to report the absorbance value with three significant figures, resulting in 0.232. Understanding the definitions and the calculation process is crucial for accurate conversions.

1. A solution exhibits 58.8 of %Trasmittance value. Convert this value to absorbance. Report with Three significant figures.




Not sure how to do this?? Do I subtract 100 percent from 58.8 I have no clue what to do lol..

Check definitions of both.
 


ahhh found it I actually found a table for it but I am still lost in how to do the math for it lol
