1. Use Excel (or some other spreadsheet program) to plot density versus concentration for the five reference solutions on a graph. The concentration is the independent variable (x-axis) and the density is the dependent variable (y-axis).
2. Add a “best-fit” line to your plot and display the line equation for this “best-fit” line on your plot.
3. Use the line equation for the “best-fit” line to calculate the percent concentration of sugar in the beverage solution.
4. Calculate the actual or accepted value of the sugar concentration in weight percent for each beverage, using the nutrition label information and the measured density value. Hint: See Pre-Lab Question #3 for how to do this calculation. Record both the nutrition label information and the actual percent sugar concentration in your Results Table.
5. Use the following equation to calculate the percent error in your experimental determination of the sugar content in each beverage. Enter the percent
