Given
ColorName                          Chemical formulamass of dyevolume of solution
FD&C Blue 1ErioglaucineC37H34N2Na2O9S30 .06343 g        1.000 L
FD&C Yellow 5Tartrazine         C16H9N4Na3O9S20.1860 g        1.000 L


Each of the dyes will carry out the following dilution scheme:

Dilution #1 = 5 mL of stock + 45 mL water
Dilution #2 = 30 mL of #1 + 20 mL water
Dilution #3 = 35 mL of #2 + 15 mL water
Dilution #4 = 30 mL of #3 + 20 mL water

So Molarity must be found of the stock solution and the dilutions of Erioglaucine and Tartrazine.

I am totally lost on this, any help is appreciated.

Shred whatever paper asked you this question, burn it in a fire and call it chemistry.

0.06343 g/ 1.000 L * 0.005 L/0.05 L

Rinse and repeat.
