Unformatted text preview: What limits the linearity of a Beers Law plot? In comparing the 444 nm data obtained from the HP 8452A and the Genesys20 spectrophotometers, which instrument is more precise? Which instrument is more accurate? In addition, answer the following questions: 1. A solution of riboflavin has an absorbance of 0.438 AU at 444 nm. What is the concentration of the riboflavin solution? 2. A solution of riboflavin has an absorbance of 3.48 AU at 444 nm. After diluting 1.000 mL of this solution to 10.00 mL, the absorbance of the diluted solution was measured to be 0.576 AU. What is the riboflavin concentration of the original (undiluted) solution?...
