- To run a spectrophotometry experiment, begin by warming up the spectrophotometer and preparing the samples. Be sure to select the correct absorbance (X), then run a measurement on the sample solution. Follow up by running measurements on sample solutions. Once data is collected, turn off the instrument, clean the area, and discard the samples. Partially correct (2 of 4 correct)1. Take your data home and use EXCEL to prepare a Beer's Law plot of the data from your standards (Trials 1-5). You should plot Absorbance on the "y" axis and concentration on the "x" axis. Include a print out of your graph with your report. 2. Add a trend line to your graph in the same way that you added the trend line to the graph you prepared in your density experiment (EXP 1). Be sure to show the equation the line on your graph. 3. Utilize your graph to determine the concentration of your unknown copper sulfate solution. Show how you did this on your graph.
