- * You can keep extra decimal places through most of this problem, but round your final estimate to one decimal place* You wish to quantify your favourite compound in an experimental solution using spectrophotometry. First, you use standard solutions of your favourite compound to collect the following standard curve data. Calculate the slope of the line of best fit. Standard curve data Conc (mM) 0.300 0.600 0.900 1.200 1.500 Abs 0.150 0.300 0.450 0.600 0.750 Next, you prepare an experimental sample by mixing 0.50 mL of the compound solution with 9.50 mL of distilled water, and you read an absorbance of 0.625 for this sample. Calculate the concentration (mM) of the original solution of compound. Round this answer to one decimal place.DATA Determine the Molar concentration of your dilutions using the formula M₁V₁ = M₂V₂.

- This is a question regarding spectrophotometry. Scenario: 0.1 mL of the unknown and 0.9 mL of distilled water are mixed in a cuvette and the absorbance is measured at 280 nm. Given the absorbance, molecular mass and the extinction coefficient of the unknown are 0.253, 16950 g and 13940 M-1cm-1 respectively, and the path length is 1 cm, how can I find the concentration of the unknown in mg/mL by Beer-Lambert Law (NOT molarity M)?6. GENERALIZATION Direction Arrange the procedure given below in order in preparing a solution. Use the box on the right. Write your answer on a separate sheet of paper. 1. Preparation of a Standard Solution The solid is dissolved in the water (1) by gently swirling the flask (with the stopper in place). A weighed amount of a substance (the solute) is put into the volumetric flask. More water is added, until the level of the solution reaches the (2) mark etched on the flask A small quantity of water is added to the solute. (3) (4)2. Compute for the calibration factor.
