Question

The chemical formula of a particular compound represents:

• A. the size of molecule
• B. the shape of its molecules
• C. the total number of molecules in the compound
• D. the number of different types of atoms in its molecule

Answer 1

The correct option is D the number of different types of atoms in its molecule

The chemical formula of a particular compound represents the number of different types of atoms in its molecule. For instance, the compound $C{O}_2$ (carbon dioxide) has one carbon atom and two oxygen atoms. It does not represent the size or shape of the molecule or the number of molecules in the compound.
