Section 8: Molar Mass
Molecular Formula, Molar Mass Conversions, Percent Composition, Empirical Formula, Molarity
The way that the amount of a particular compound is measured is mass. Once a mass has been measured, the periodic table is then used to determine the amount of a substance there is. The molar masses of each element in the compound are then added so that the mass of the compound is then reached. One of the methods that is used to determine unknown compounds is finding the percent composition. Once it has been determined the percentage of a particular element in a compound, the formula of the compound can then be extrapolated. The empirical formula is a formula that has the lowest possible ratio between elements.
