Web13 practice problems covering average atomic mass. Students will calculate the amu of elements, relative abundance, and use mass spec data to also determine the identity of an element. Mass spec data was produced using MS Word tools. Answers and solutions are provided. Doc can be edited to add, remove, or modify questions. WebTwo other common elements having useful isotope signatures are carbon, 13 C is 1.1% natural abundance, and sulfur, 33 S and 34 S are 0.76% and 4.22% natural abundance respectively. For example, the small m/z=99 amu peak in the spectrum of 4-methyl-3-pentene-2-one (above) is due to the presence of a single 13 C atom in the molecular ion. …

The abundance of the chemical elements is a measure of the occurrence of the chemical elements relative to all other elements in a given environment. Abundance is measured in one of three ways: by mass fraction (in commercial contexts often called weight fraction), by mole fraction (fraction of atoms by numerical count, or sometimes fraction of molecules in gases), or by volume fraction. Volume fraction is a common abundance measure in mixed gases such as planetary at…
