Question

Note: 10 drops of red dye is equal to 0.50 mL, and the initial concentration of the FD&C red dye in the pipet is 0.0201 M.

Review the following equation M1V1 = M2V2 , where M1 is the intial concentration, V1 is the intial volume, M2 is the final concentration and V2 is the final concentration. 

Use the M1V1 = M2V2 equation to calculate the final concentration of red dye in each of the test tubes. Record the final concentrations for each test tube.

17 Fill each of the eleven test tubes with the standard red dye and distilled water, as described in Table 1. For example, in test tube 1,
use the pipet in the standard red dye to fill the 10 mL graduated cylinder with 4.5 mL of the standard red dye. Then, use the pipet in
the distilled water to fill the graduated cylinder to the 5.0 mL mark with distilled water. Finally, carefully pour the contents of the
graduated cylinder into the test tube labeled 1"
