Concept:The empirical formula gives the simplest whole-number ratio of atoms of each element present in a compound.
Explanation:This ratio is reduced to its smallest possible whole numbers.
Hence, the empirical formula is also called the simplest formula.
For example, glucose has the molecular formula
C6H12O6, but its empirical formula is
CH2O.
The empirical formula does not always show the actual number of atoms in one molecule.
The molecular formula may be a simple multiple of the empirical formula.
A generic chemical formula can refer to any type of formula, including molecular or structural.
A structural formula shows how atoms are connected in space.
Only the simplest formula describes the smallest ratio of atoms.
Answer:A. simplest formula of a compound
