Definition of molecular formula in US English:

molecular formula

noun

Chemistry

A formula giving the number of atoms of each of the elements present in one molecule of a specific compound.
Compare with empirical formula, structural formula
Example sentencesExamples
- Isomers are nothing more than two or more compounds that have identical molecular formulas, but different chemical structures and physical properties.
- The molecular formula, showing the exact number of each kind of atom, can be determined in several ways, but discovering the arrangement of these atoms requires a large amount of detective work.
- They have 8-13 carbon atoms in their molecular formula.
- Elemental analysis is often used to confirm the molecular formula deduced from spectroscopic experiments.
- Special kinds of chemical formulas, called molecular formulas, are used to represent the kinds of atoms and the number of each kind of atom in a molecule.
