Mass spectrometry past paper questions

Chemistry 9701 · Analytical techniques. 1 analyse mass spectra in terms of m/e values and isotopic abundances (knowledge of the working of the mass spectrometer is not required) 2 calculate the relative atomic mass of an element given the relative abundances of its isotopes, or its mass spectrum 3 deduce the molecular mass of an organic molecule from the molecular ion peak in a mass spectrum 4 suggest the identity of molecules formed by simple fragmentation in a given mass spectrum 5 deduce the number of carbon atoms, n, in a compound using the [M + 1]+ peak and the formula n = 100 × abundance of [M + 1]+ ion
