What is the relative atomic mass of an element with the mass spectrum shown in Figure 2.2? A mass spectrum plot with 'Relative abundance' on the vertical axis and 'Mass:charge ratio (m/z)' on the horizontal axis. The horizontal axis has tick marks at 69, 70, and 71. There are two vertical bars representing peaks. The first peak is at m/z 69 and has a height corresponding to 60.1% relative abundance. The second peak is at m/z 71 and has a height corresponding to 39.9% relative abundance. A label 'area under peak' with a dashed line points to the top of the m/z 69 peak.| Mass:charge ratio (m/z) | Relative abundance (%) |
|---|---|
| 69 | 60.1 |
| 71 | 39.9 |
