Unformatted text preview: for each element in the empirical formula. 6. Be able to do this in reverse! Mass Spectrometry and Molecular Mass All mass spectrometers separate atoms and molecule by first converting them into ions and then separating those ions based on the ratio of their masses to their electric charges. Determining the Molecular Formula Must be an integer factor of the empirical mass Multiply all subscripts in the empirical formula by the same factor Can be determined from the percent composition and mass spectral data...
