Interpretation Introduction

(a)

Interpretation:

Theabsorbance of the solution for the percent transmittance for half of 5.38% is to be calculated.

Concept introduction:

The absorbance of the solution is the ability of the solution to absorb the monochromatic light passing through it. The absorbance of the solution is defined as the ratio of the intensity of light incident on the solution to the intensity of light absorbed by the solution.

The relation between the absorbance and transmittance of a solution is given by Beer’s law.

How does pipetting laboratory techniques affect absorbance values when using UV-Vis Spectrophotometry?
A student prepared several solutions of an unknown molecule, each at a different concentration. The absorbance of each solution was measured at 630 nm with a path length of 0.760 cm. The student then plotted the absorbance of each sample vs. its concentration (in uM), and found a best-fit line of y = 0.00626x + 0.00732. Calculate the molar absorptivity of the unknown molecule (in M-1 cm-1).
The molar absorptivity for Blue #1 dye is 1.30105 M‒1 ·cm‒1 at 629 nm. Calculate the expected absorbance of solution of Blue #1 with a concentration of 4.50×10–6M when measured at 629 nm in a 1.50 cm cell.
