The regression line from a plot of absorbance vs. concentration yields: 𝐴 = 2.31[𝐶] + 0.002. If the absorbance of an unknown is measured to be 0.124, what is the concentration of the analyte [𝐶]?

Answer 1

A = 2.31C + 0.002
0.123 = 2.31C + 0.002
(0.123-0.002)/2.31 = C
You solve it.

Answer 2

Thankyouuu.
