SOLVED: Detection limit. In spectrophotometry, we measure the concentration of analyte by its absorbance of light. A low concentration sample was prepared, and nine replicate measurements gave absorbances of 0.0047, 0.0054, 0.0062, 0.0060, 0.0046, 0.0056, 0.0052, 0.0044, and 0.0058 in a 1.000-cm cell. Nine reagent blanks gave values of 0.0006, 0.0012, 0.0022, 0.0005, 0.0016, 0.0008, 0.0017, 0.0010, and 0.0011.(a) Find the absorbance detection limit with Equation 5-2.(b) The calibration curve is

The concentration of many colorful solutions can be determined by the amount of light absorbed by the solution. The relationship between absorbance and concentration is a linear relationship known as Beer's law. The data below show the absorbance of a series of solutions of known concentrations of Substance A. Plot these data using Excel and determine the equation of the trendline. Use that equation to determine the concentration (M) of an unknown sample of Substance A.Concentration of Substance
