ObjectiveTo determine the molar absorptivity of inosine and adenosine as well as to calculate a data analysis of the class data. From Dr. Hartings ProcedureA new adenosine stock was repeated, using this procedure from yesterday. An adenosine stock solution of 3.03x10-3 M was created using 0.0809 g of adenosine. From there, new dilutions were made to the same concentrations as yesterday. Figures
Matt Hartings For these spectra, why does the baseline go below zero? Do these need to be re-corrected to increase all of the values?
NotesThe data our group collected yesterday for inosine was systematically lower than the rest of the class data. For this reason, our inosine data was not included in the class data. The adenosine trial from yesterday was also systematically lower than the class data. We remade the stock solution and ran the sample dilutions again. The resulting data was closer to the class data, so the first trial was discarded. | |
