Molecular formulas describe the exact number and type of atoms in a single molecule of a compound. The constituent elements are represented by their chemical symbols, and the number of atoms of each element present in each molecule is shown as a subscript following that element's symbol.
The empirical formula of a compound is also called the simplest formula. It. represents the relative or smallest whole-number ratio of atoms in a cmpd. 2. The molecular formula represents the actual number of atoms of each element. in a molecule of the compound. 3. The empirical formula and the molecular formula are mathematically related as. follows: Molecular formula = n x empirical formula.
