Percents come up several times in chemistry. Remember that the key is to change a percent to a number before calculating with it and, ... When measuring a sample for its constituent parts, the amounts of each part are often stated as %s -- you'll see this in percent abundance of isotopes and in percent composition of compounds.

Isotope abundance At this point it would be useful to reduce the number of possible formulas. One way to do this is by looking at the intensity of ... Combustion Analysis. This verifies the high resolution mass spectrometry results. You should be able to verify our results by calculating the percent elemental composition.
