What is the concentration of yellow 5 and red 40 in an unknown sample? and what is hte mole ratio?

Question

.1234g of orange kool-aid is dissolved in .1 L of water. The absorbance due to yellow 5 and red 40 are A @ 427 nm = .610 and A @ 503 nm = .159.

What is the concentration of each dye?

What is the mole ratio? (moles Y5 / moles R40)

Answer 1

use beers law to figure out the concentration and then take that to mole ratio
