The following data set describes the visible spectroscopy
absorbance readings (at 565 nm) for a series of violet solutions.
Use a computer (Excel, Google Sheets, etc.) to generate a
calibration curve (10 points). Be sure your plot includes a title,
axes labels, units, all of the data points, and a trend line.
Recognize that when the concentration = 0, the solution is clear
and colorless. Attach the plot as a separate page in this document
to submit to the course...
