FAQ Insights
What is the purpose of an empirical formula?
An empirical formula represents the simplest whole-number ratio of elements present in a compound, providing insight into its elemental composition.
How do I determine the empirical formula of a compound?
To determine the empirical formula, you need to know the mass or mole fractions of each element present in the compound and then simplify the ratios to the smallest whole numbers.
What is the difference between an empirical formula and a molecular formula?
An empirical formula represents the simplest whole-number ratio of elements, while a molecular formula indicates the actual number of atoms of each element in a molecule.
