1.2 Mass Spectra of Elements
IntermediateMCQMathematicalConceptual19.1k
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.

IsotopeIsotopic 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 \(\text{X}\)?
