(a) Interpretation: The compound that is soluble in water among naphthalene (C 10 H 8 ) or hydrogen peroxide (H-O-O-H) should be identified. Concept introduction: Solubility depends on the solvent and solute having same intermolecular bonds. Hence, the polar compounds are soluble in a polar solvent and nonpolar compounds are soluble in non-polar solvents.

Question

A 365 µM solution of a dye molecule, Rhodamine 6G, dissolved in methanol is allowed to sit open to the air such that the volume of the solution is reduced to 43% of its original volume due to evaporation of methanol. Assuming that no dye molecules are lost during the evaporation process, what is the concentration of the dye in the remaining ethanol after evaporation?
