Pearson Edexcel IAL Chemistry AS 2.7 Diatomic molecule mass spectra
Pearson Edexcel IAL Chemistry AS 2.7 Diatomic molecule mass spectra
Practise predicting molecular ion peak positions and relative heights for chlorine or bromine using isotope masses and abundances.
How this is tested
- draw Cl2+ or Br2+ molecular ion peaks at the correct m/z values from isotope masses
- use isotope abundances to give relative peak-height ratios
- calculate relative molecular mass for a diatomic sample from isotope percentages
