It can also be used for identification of molecular samples as well. Consider, for example, the mass spectrum of pentane (Figure 5): Lifie relative abundance 57 29 72 10 20 30 40 50 60 70 miz Figure 5. Pentane Mass Spectrum The pentane molecule (CH;CH,CH;CH;CH; or C;H12) is a straight-chain hydrocarbon. In Figure 5, notice there are four groups of peaks. This forms what is known as the cracking pattern of the molecule. The first peak is at m/z = 72, corresponding to the molecular ion, C;H,2", where only one electron was knocked off the pentane molecule. The three peak groups are from fragments of pentane created in the ionizer: m/z = 57 (CH;CH,CH,CH,"), m/z = 43 (CH;CH,CH;"), m/z = 29 (CH;CH,"). These species have had pieces of the molecule knocked off in addition to losing an electron. 4. For the peak at m/z = 43, what part of the pentane molecule was knocked off? Use…arrow_forwardyou are to determine the molecular formula for a molecular compound consisting of only carbon & hydrogen. The molar mass of this compound is 42.08 g/mol. Part D: The empirical formula has a molar mass of 14.026 g/mol (this is called the empirical molar mass). Divide the molar mass for the total compound given above by the empirical formula molar mass. This will give you a number for multiplying the carbon atoms and hydrogen atoms in the empirical formula. What is the multiplication value?arrow_forward
