Chemistry

Calculate the exact masses and relative isotopic abundances ofall the isotopomers of dichloromethane. Consider only the two mostabundant isotopes of carbon and chlorine, and ignore deuterium andtritium (i.e., assume the natural abundance of 1H is 1.000000).Summarize your results by giving in a table the empirical formulafor each isotopomer with superscripted atomic masses, the nominalm/z and the exact m/z values for each in a table .

To calculate natural abundance, make a product of the naturalabundance of each element raised to the power of the number oftimes it occurs in the molecule. Then multiply it by the number ofdistinguishable ways that you can make this isotopomer, if thenuclei are labelled. For example, for two C nuclei labelled A andB, there is only one way to make 13C-13C (13CA13CB) but there aretwo ways to make 12C-13C (i.e., 13CA12CB and 12CA13CB). When you’redone correctly, all the abundances should add up to 100%, so youcan use this to check for errors.
