Using Beer Lambert Law to find the concentration of a solution. When the absorbance is measured. You will need to do a graph and linear analysis for this. Below are five pairs of data, absorbance and concentration. Estimate the slope of the line either using graph paper and a ruler or by using graphing software that does linear regression. Once you have completed the graph, estimate from the line what the concentration of the unknown would be. Report the values of the unknown concentration with units. You can refer to the lab procedure at the KCC website or youTube videos to find more details on linear regression. You can also Google videos on “Beer-Lambert Law”. This process is called “linear interpolation” and you can also research that to help you figure this one out. Data Concentration (moles/Liter) Absorbance 0.010 0.115 0.020 0.226 0.030 0.349 0.040 0.441 0.050 0.583 Unknown solution ______ 0.322
