3. Use the Beer’s law plot and best fit line to determine the concentrations for samples:
M21050-1, M21050-2, M21050-3, M21050-4, M21050-5.
4. The company reported that sample M21050-2 has an M concentration of 0.0003 M. Assuming
that the results in Question 3 are 100% accurate and without error, is the company’s statement
accurate? What is the percent error between the reported concentration and the concentration
calculated in Question 3?
5. By law, Drug Company Q must have an M concentration between 2.85 x 10
M and 3.15 x 10
M. Do all samples analyzed meet the legal requirements? Use the information from
