Read the detailed procedure of an experiment in your screen. Evaluate each step in the procedure whether it belongs to HOMOGENIZATION, EXTRACTION, PURIFICATION/CONCENTRATION, DATA TREATMENT, or INSTRUMENTAL ANALYSIS step.
A student weighed out 0.150 g of protein powder and dissolved it in 100 mL of water (Solution 1). The student then diluted this solution by transferring 1 mL into a 25 mL flask and diluting with water (Solution 2). Finally, 1 mL of that solution was transferred to a test tube and combined with 4 mL Bradford reagent. The absorbance of the solution in the test tube was 0.187. Assuming that the best fit linear line of the standard curve was y = 0.04144 x + 0.01521 (μ g mL), calculate the percent protein by mass in the original protein powder.
