Answer 1

O the molecular formula

Step-by-step explanation:

The true ratio of atoms in a molecule or formula unit is called the molecular formula.

The molecular formula of a compound shows the true number of atoms that are combining to form a compound.

For example, the molecular formula of water is H₂O.

• Empirical formula of a compound is its simplest ratio.
• When the number of atoms are divided by the smallest possible factor, it yields the empirical formula.
