The simulation below contains 5 standard solutions of Red #40. The undiluted concentration of the red dye is 3.2x10-5 M. As with the blue dye, the solutions are in concentrations of 100%, 80%, 60%, 40% and 20%. Use the data provided by the simulation to fill out the table and create a calibration graph for Red #40. Once you have completed the graph and table, you can use them to determine the concentration of dye in your drink. dilution Absat Absorbance D The measurement is finished, please remove the old vial before inserting the new one 0.00 20 0.267 40 0.50S 0.267 60 0.796 8 30 1.026 100 1.270 Wavelength (nm) KOLAB FAST SOW K:100% RED 40 Repp Your drink sample has the following absorbance reading: 0.833 at the analytical wavelength 505nm Using your graph, determine the molar concentration of Red #40 in your drink sample. (Note: please enter your answers to 2 significant figures, for very small numbers, you may use scientific notation: le 0.00023 can be entered as 2.30 en spaces) NA The concentration of Red #40 in your drink is: M Checo
