Erioglucine is a blueÂcolored dye that absorbs its complementarycolor, red, in aqueous solution around 645 nm. Unfortunately, thelocal distilled water supply is consistently contaminated with atrace amount of a metal cation that also absorbs 645 nm light.Suppose then, a control sample of 0.0552 M erioglucine (aq; samewater supply) has an absorbance of 0.331 and that a distilled watersample in a similar cuvette has an absorbance of 0.019. Determinethe concentration of an erioglucine (aq) sample (same water supply)that has an absorbance of 0.237. Concentration: _____ M
