Answer:
The concentration of dye is 2.29 mg/mL.
Explanation:
According to Beer's law the absorbance (A) of a solution is proportional to its concentration (c). The best fit curve line to an A vs. c plot has a slope of 0.1815 mL/mg and intercept of 0.0477. The resulting equation is:
A = 0.0477 + 0.1815 mL/mg . c
If a solution has an absorbance of 0.464, the concentration of dye will be:
0.464 = 0.0477 + 0.1815 mL/mg . c
c = 2.29 mg/mL
