1.2 Mass Spectra of Elements
A sample of a naturally occurring element, \(\text{X}\), is vaporized, ionized, and analyzed in a mass spectrometer. The mass spectrum yields two distinct peaks corresponding to \(\text{X}^+\) ions, with the data summarized in the table below.
Based on the data in the table, what is the average atomic mass of element \(\text{X}\)?
| Isotope | Isotopic mass (\(\text{amu}\)) | Relative signal intensity |
|---|---|---|
| \(^{63}\text{X}\) | \(62.93\) | \(7.0\) |
| \(^{65}\text{X}\) | \(64.93\) | \(3.0\) |
Based on the data in the table, what is the average atomic mass of element \(\text{X}\)?
