can you help me answer this question

Do It Yourself - Graphing and Plotting Data When bromothymol blue, an acid/base indicator, is dissolved in dilute hydrochloric acid it turns yellow in color. The data in the table below was collected to determine the relationship between absorbance of this protonated yellow species at 453 nm and its concentration. In a buffered green solution of bromothymol blue, the amount of the protonated version can be determined by measuring the absorbance at 453 nm. For the green solution, the absorbance at 453 nm was 0.177 a.u. (Recall that A = ebc) [bromothymol blue] M | A at 453 nm 5.00E-06 0.086 7.50E-06 0.119 1.00E-05 0.145 2.10E-05 0.325 1.38E-05 0.208 The concentration of the protonated yellow species is: M Preview
