Question

An aqueous solution absorbs 10% of incident light passed through it. Calculate the absorbance if the same solution is placed in a cell 5 times as thick?

Answer 1

Beer's Law states that the Absorbance (A) is (among other variables) dircetly proportional to the path length of the light (the thickness of the cell).  So, if the cell is 5 times as thick then the absorbance would be 5 times greater (50%)
