Plot the data:
a. Graph density (r-axis) vs. mass % (x-avis). The data point for deionized water (0% CaClh) should
also be included on the graph.
b. Scale and label each axis properly, title the graph appropriately.
c. Include best-fit linear trendline and equation on graph.
Determine Mass% CaCh in unknown solution from trendline equation on graph:
