Lab Report Assistant: This document is not meant to be a substitute for a formal laboratory report. It is simply a summary of the experiment’s questions and data tables which should be addressed in a formal lab report. The intent is to facilitate student’s writing of lab reports by providing this information in an .rtf format which can be copied and pasted into an electronic document. Beer’s Law & Colorimetry Part 1: Beer's Law: 1. Prior to analyzing the samples provided by Q you must demonstrate (for yourself and others) that you, your instruments, and your company will produce reliable results. One of the ways you decide to do this is by making a Beer’s law plot using pure M. You obtain the following data: Sample Identification Code Concentration of M (mol/L) %T A Q5000 4.00 x 10 -4 17.9 Q5001 3.20 x 10 -4 25.0 Q5002 2.40 x 10 -4 35.7 Q5003 1.60 x 10 -4 50.2 Q5004 8.000 x 10 -5 70.8 Convert %T to absorbance and prepare a Beer’s law plot using these data. 2. You are now ready to begin analyzing the drug. You are sent five bottles of the drug from batch 021015. You analyze these samples and obtain the following data: Sample Identification Code %T A Q021015-01 43.7 Q021015-02 44.1 Q021015-03 43.8 Q021015-04 44.1 Q021015-05 43.8 What is the concentration of M in these samples?
3. Company Q has reported that batch 021015 has an M concentration of 3.00 x 10 -4 mol/L. Your analysis is better than theirs; therefore, you assume that your analysis is correct. What was their percent error? Remember from Chemistry 1, that formula is: % error = theoretical value – actual value x 100% theoretical value 4 By law, company Q must have an M concentration of 3.00 x 10 -4 mol/L +/- 5%. (In other words, the M concentration must be between 2.85 x 10 -4 mol/L and 3.15 x 10 -4 mol/L.) Does Batch 021015 meet legal requirements?
