Determination of a chemical formula

1 experiment 12: empirical formula of a compound introduction chemical formulas indicate the composition of compounds a formula that gives only the simplest ratio of the relative number of atoms in a compound is the empirical formula or simplest formula. Determining the molecular formula molecular ion using mass spectrometry to determine the molecular ion allows us to identify possible molecular formulas in the 70 ev ei spectrum, the highest m/z ion appears to be m/z 154 in the 13 ev ei spectrum, less fragmentation is observed because the ionization energy is much lower. Titration formula the equation above can be used to determine the unknown concentration is 1:1 as determined by the balanced chemical equation. Chemical formulas are used to indicate how new compounds are formed by chemical reactions if the chemical formula of a substance is its molecular formula.
