Qualitatively, how could you use a spectrophotometer to easily determine whether a green drink sample contains green dye molecules or a combination of both blue and yellow dye molecules? Be as specific as possible in your explanation.

Answer is in the explanation

Explanation:

A spectrophotometer is an instrument used in chemistry to measure the absorbance of a sample in an unique wavelength of light showing a complete spectrum.

When you measure in a spectrophotometer a green drink sample you will see a spectrum with just one peak if the sample contains just green dye molecules and a spectrum with two peaks if the sample contains a combination of blue and yellow dye molecules.
