a. What kind of trend or pattern is apparent from the graph of mass and volume data? Is there a consistent relationship between the volume and mass of each sample? Justify your response. b. What does the R2 value tell you about the data?

INTERACTIVE EXAMPLE The Average Mass of an Element = When a sample of natural silver is vaporized and injected into a mass spectrometer, the results are shown in the figure here. Ag-107 is present in 51.84% abundance. Ag-109 is present in 48.16% abundance. The masses of these two isotopes are Ag-107 = 106.91 u and Ag-109 108.90 u. Use this information to compute the average mass of silver. Percent Abundance -100 60 40 -20 51.84 107 Atomic Mass 109 u Submit Show Tutor Steps
