This Study Mind Tutorial covers the following specification points:

Edexcel: 1.8,1.9, 1.10, 7.1(i,ii), 19.1 (i,ii)

1.8. be able to analyse and interpret data from mass spectrometry to calculate relative atomic mass from relative abundance of isotopes and vice versa

1.9. be able to predict the mass spectra, including relative peak heights, for diatomic molecules, including chlorine

1.10. understand how mass spectrometry can be used to determine the relative molecular mass of a molecule

Limited to the m/z value for the molecular ion, M⁺, giving the relative molecular mass of the molecule.

7.1. be able to use data from a mass spectrometer to:

(i) determine the relative molecular mass of an organic compound from the molecular ion peak

(ii) suggest possible structures of a simple organic compound from the m/z of the molecular ion and fragmentation patterns

19.1. be able to use data from mass spectra to:

(i) suggest possible structures of a simple organic compound given relative molecular masses, accurate to four decimal places

(ii) calculate the accurate relative molecular mass of a compound, given relative atomic masses to four decimal places, and therefore identify a compound
