Web15 de ago. de 2024 · Because the largest m/z value is 72, that represents the largest ion going through the mass spectrometer - and you can reasonably assume that this is the molecular ion. The relative formula mass of the compound is therefore 72. Finding the relative formula mass (relative molecular mass) from a mass spectrum is therefore trivial. Web15 de ago. de 2024 · If you had a simple compound like methane, CH 4, approximately 1 in every 100 of these molecules will contain carbon-13 rather than the more common carbon-12. That means that 1 in every 100 of the molecules will have a mass of 17 (13 + 4) rather than 16 (12 + 4).
