Yes, a molecular formula shows the types and numbers of atoms present in a molecule. It uses chemical symbols to represent the elements present in the molecule and subscripts to indicate the number of atoms of each element. For example, the molecular formula for water is H2O, which means that there are two hydrogen atoms and one oxygen atom in a water molecule.

A molecular formula provides quantitative information about the elemental composition of a molecule but does not specify the structure or bonding arrangement of the atoms. For that, more advanced representations such as structural formulas or three-dimensional models are required.
