Unknown Concentration and Absorbance: At the end of the lab, you will find your unknown information. Use this information to find your specific unknown absorbance. Record the information in the space below. Use the sample dilutions, from above (page 2), to calculate a known beer's law graph. Record your concentrations and their absorbances below. Solution Absorbance Create a graph comparing the known solution Concentration concentration and absorbance. Use this graph to OM (blank) calculate the Unknown concentration (C#1). Attach your graph on blackboard. (10) Unknown code: A(from table on last page) = C #1: When finished, all your working standard solutions are to be placed in the waste container. Perform the best linear regression using Graphing calculator or Excel and report your regression equation in terms of the variables studied. Include the value of R. (5) Equation R? Using your regression equation, calculate the concentration of your unknown. Show your calculation below. (5) C#2 = Using your regression equation, Beer's Law, and only necessary information that is common to all your trials, calculate the value of the molar absorption coefficient. Show your calculation (5)
