NAMES: SECTION #: EXPERIMENT 2 BEER’S LAW Part A: Measuring the Absorbance of a Stock SolutionAssigned MiO®liquid:Volume of MiO®liquid used to prepare the stock solution:Concentration of the stock solution: mLMiO/mLSolnValue of maxof the stock solution:Wavelength set on the colorimeterto measure the absorbance of the stock solution:Average Absorbance of the stock solution:Part B: Preparing the Beer’s Law PlotComplete the table:Volume of Stock SolutionDiluted (mL)Concentration of DilutedSolution(mLMiO/mLSoln)Average AbsorbanceShow how you calculated the concentration for one of the solutions:Attach a plot of absorbance (y-axis) vs. concentration (x-axis) to this report. Use Microsoft Excel®to plot the dataincluding an additional data point of zero-absorbance (y-axis) and zero-concentration (x-axis). You should have atotal of 7 points on your graph. Add a trend line and include the equation and R2value on the graph. Do not set theintercept equal to zero. Your graph should include a title and both axes labeled with appropriate units.
