Answer to Question #106267 in Physical Chemistry for Roopali Jha

Question

While using a UV-Vis spectroscopy for concentration of the analyte of 0.11 and 0.21 mM, the absorbance read are 2 and 3 units receptively. What is the concentration if the absorbance read is 2.6 units?

Answer 1

It's a linear graph. (0.21-0.11)/(3-2) = 0.01 - step

So 2.6 represents 0.17 mM
