We were unable to transcribe this imagenumber of drops volume of solution, mL concentration, drops mL-1 (Eq. 6) For example, if the solution you use to determine the spectrum of the food dye, which we shall call "Solution 1," was prepared by adding 1 drop of food dye to 40.0 mL of distilled water, the concentration of the solution is found using Equation...

Absorbance vs. Wavelength (A vs. A) Absorption Spectrum Peaks for the Diluted Grape-Flavored Drink Peak Amax Absorbance, A 507 nm 0.387 608 nm 0.528 1. Preparation Tables (9 p). Working with a stock solution of FD&C food dye Red #40 (3.55 x 10M) and another stock for FD&C food dye Blue #2 (3.79 x 10 M), you build two dilution sets using NANOpure water as diluent. Complete...

Red Food Coloring Absorption Spectrum 1.000 0.800 0 600 0.400 0 200 400 450 500 Sso 600 650 3a. If the molar absorptivity constant at the optimum wavelength for the red dye solution is 5.56x104 M-lcm1, calculate the molarity of the red dye solution based on the absorbance value you obtained in question #2. You may assume L-1.22cm. Hint: A-ELC Molar mass of FD&C #3 = 879.86 g/mol b. Convert the molarity in part a to w/v00. Show your work....
