Suppose a student carried out a similar experiment using Fast Green FCF, a food dye. Using a stock solution, the student created four standard solutions to measure the absorbance at , and construct a calibration curve. \table[[Sample,Dye concentration ,Absorbance],[1,0.0200,0.860],[2,0.0150,0.645],[3,0.0100,0.430],[4,0.0050,0.215]] The student then measured the absorbance of a sample of Fast Green FCF with an unknown concentration at . The absorbance for the unknown solution of Fast Green FCF was 0.444 . Calculate the concentration of the unknown Fast Green FCF solution. concentration:
