Using your knowledge of the dilution process, compute the molarity for each of the dilutions. M 2nd trial M Graph the data using Molarity as the independent variable and the absorbance as the dependent variable. By graphing the two sets of data on one graph, the trials serve as a cross check. It is reasonable to identify the separate trials, however, to provide this comparison. The absorbance reading and calculations also provide a check.
Some measures however are critical to the entire experiment.
The initial standard is one of these. Each dilution also depends upon all prior solutions. In your report, you should be able to identify and describe the impacts of both types of errors, one time and those with multiple impacts. You should also be able to gauge the dependability of Beer s Law.
