Chemistry how to find concentration
WebJan 30, 2024 · The absorbance is directly proportional to the concentration (\(c\)) of the solution of the sample used in the experiment. The absorbance is directly proportional to the length of the light path (\(l\)), which is equal to the width of the cuvette. Assumption one relates the absorbance to concentration and can be expressed as \[A \propto c ...
