G. C. 1 - 6: LABORATORY REPORT In this lab, we will use the principle of Beer’s Law to determine the exact concentration of the dye in a Powerade drink solution YOU MUST SHOW ALL YOUR CALCULATIONS TO RECEIVE CREDIT FOR THEM! Proper use of significant figures and units is part of the grading. Data table for the dye solutions: Please record the absorbance values from the video posted under the instructional materials in your canvas page. SOLUTION # VOLUME OF STOCK DYE SOLUTION (mL) VOLUME OF WATER (mL) MOLARITY ABSORBANC E 1 2.00 8.00 0.08 0.045 2 4.00 6.00 0.16 0.249 3 6.00 4.00 0.24 0.440 4 8.00 2.00 0.32 0.611 5 10.00 0.00 0.40 0.704 Powdered drink solution 0.237 0.412 Data Processing 1. Calculate the molar concentrations of the diluted solutions and record them on your data sheet. 2. Draw a calibration graph of absorbance vs. concentration by using excel for these data. 3. Determine the concentration of the powdered drink solution from the excel graph.
