Optical absorbance at 260 nm is routinely used to measure the concentration of nucleic acids present in a solution. Approximate conversion factors estimate that duplex DNA is about 50 μg/OD 260 , single-stranded RNA is approximately 40 μg/OD 260 , and single-stranded DNA is approximately 33 μg/OD 260 . To understand how to calculate equilibrium concentration using the equilibrium concentration equation, you need to know the formula for equilibrium constant K c. When the chemical is in equilibrium, the ratio of the products to the reactants is called the equilibrium constant. 2018-06-08 If the transmittance of an unknown solution is 0.735, what is the concentration of the unknown KMnO 4 solution in ppm.

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 \[A \propto c \label{1}\]
