(When answering this problem, report the answer with the appropriate number of significant figures. When entering units, use proper abbreviated units with proper capitalization.)
A beverage drink mix sample is prepared by mixing a packet of beverage powder in a gallon (3.78 L) of water. A sample for analysis is prepared by diluting 10.00 mL of this solution in a 50.0 mL volumetric flask. When measured using a colorimeter, this diluted solution has an absorbance of (3.49x10^-1).
The calibration curve for the experiment yielded a linear fit of y = 21655x+(1.7950x10^-2) and an R2 value of 0.9911.
Determine the molar concentration of food dye in the analyzed sample.
Hint: The answer is assumed to be reduced to the highest power possible.
