Please answer the question correctly is all I want and explain why its thats answer for the final and please answer as quickly as possible, thanks! You graph the calibration curve of a solution of an unknown metal (we will call it M+) at 400 nm. The graph is shown below. What is the absorbance of a 80 mmol/L solution of the metal at 400 nm?

5) compare your calculated AH value with a published value.

Can someone help me interpret this data to be put on my research paper? This is the absorbance spectrum fo Sulfamethoxazole (sulfonamide antibiotic). Thank you so much!

Project 2: Food Dye Spectroscopy Which scale (percent transmittance or absorbance) is most useful for collecting data from the spectrometer? Why?

Reset Help Using a spectrophotometer, it is possible to monitor the reaction by measuring the changing increase concentration of reactant Group 1 or product Group 1 as it progresses. remain constant A decrease First, the extinction coefficient (ɛ) must be determined for all visibly active species by measuring absorbance the Group 3 of each on a spectrophotometer at Group 4 concentrations. B temperature m. These measured values would Group 2 for the reactant and Group 2 for the product known as the reaction progresses in accordance with the Beer-Lambert law (A = ɛbc). unknown Comparing how the concentration of the product changes with respect to the concentration of the reactant would allow for the exponent Group 1 to be determined.

You graph the calibration curve of a solution of an unknown metal (we will call it M+) at 400 nm. The graph is shown below. What is the concentration the solution with an absorbance of 0.500 at 400 nm?

3. Using the data at right: a. Calculate the absorbance of each sample. You will need to express the %T values as decimals before calculating the logarithms. (e.g., for T = 25%, A = -log 0.25 = 0.602) b. Use the graph paper on the back of this page (or a spreadsheet) to plot absorbance vs. concentration. Make a proper graph, with labeled axes, uniform scales, etc. Use a ruler to draw the best-fit line.. C. Use the graph to find the concentration of the un- known sample. (Draw dotted lines on the graph showing how you found your answer.) CONCENTRATION PERCENT (ppm) TRANSMISSION 0 100.0 100 74.1 200 54.9 300 40.7 400 30.1 500 22.3 unknown 31.6 ABSORBANCE
