Question

Assuming that the standard solution contains 20.0 g/L of Red Dye #40, report the concentration in g/L of Red Dye #40 in your unknown.

The path length is 1.00cm

To test the unknown and standard solution, 0.1 mL of the unknown was dispensed into a 50-mL volumetric flask about three-fourths full with deionized water. this was done 1 more time for the unknown and two times for the standard solution. Therefore at the end, there were 4 flasks each with 0.1 mL of sample (2-unknown and 2-standard solution).

This is your experimental data for Experiment #4, Autopipette and UV/Visible Spectroscopy.
YOU MUST READ THE EXPERIMENTAL WRITE-UP AND COMPLETE THE PRE-LAB PRIOR TO DOWNLOADING THIS DATA!!
Your unknown number is: 1290
You made your standards, and when you measured them on the UV/Visible Spectrophotometer produced the following data:
The first standard solution has an absorbance of 0.8783
The second standard solution has an absorbance of 0.8830
The first unknown solution has an absorbance of 0.6486
The second unknown solution has an absorbance of 0.6486
