Catra wanted to determine the concentration of copper(II) chloride at an unknown concentration .She began by trying to determine the value of epsilon (ε) using beers law for copper(II) chloride. Catra remembered in lab when they wanted to solve for epsilon they would test the absorbance for three different concentrations of a known solution and then graph it. Catra got frustrated and asked Shera what to do next to determine epsilon. What should Shera tell Catra?

Pre-Lab Questions 1. Define a protein, and describe one important function of proteins in the human body. 2. The following data were obtained from a Bradford assay to determine the protein content in a sample: Protein content (ug) Absorbance value 0 0.000 2 0.022 5 0.065 10 0.106 20 0.178 30 0.299 40 0.380 50 0.472 unknown 0.150 Use Excel, another program, or graph paper to produce a calibration curve based on the data. Use linear regression (or best fit line) to obtain the slope of the line. Determine the unknown protein content for a sample that shows an absorbance reading of b. С. 0.150.
