Using the data below please make two graphs with Excel (or a similar program).
1. Absorbance (v-axis) vs. A (x-axis) for the absorbance curve of the dye solution. Connect the points with a smooth curve.
2. Absorbance (y-axis) vs. concentration (x-axis) for the Beer's Law data. Draw a best-fit line or use a program such as Excel and do a least-squares fit to determine the best-fit line through the points.
please answer super super fast please please need it now its urgent just creat the graphs
