Scenario: First, 0.1 mL of the unknown is mixed with 0.1 mL of distilled water. Then, 0.1 mL of the solution and 0.9 mL of distilled water are mixed in a cuvette and the absorbance is measured at 410 nm. Given the absorbance, molecular mass and the extinction coefficient of the unknown are 0.650, 16950 g and 188 mM-1cm-1 respectively, and the path length is 1 cm, how can I find the original concentration of the unknown in mg/mL by Beer-Lambert Law (NOT molarity M)?
