Answers
A chemical formula based on actual number of molecule is called B) MOLECULAR FORMULA
EXPLANATION :
A) STRUCTURAL FORMULA : A formula that indicates not only the number of atoms, but also their arrangement in space.

B) MOLECULAR FORMULA : A formula that describes the exact number and type of atoms in a single molecule of a compound.
EXAMPLE : The molecular formula for glucose is C6H12O6. The molecular formula indicates the exact number of atoms in the molecule.
C) EMPIRICAL FORMULA : A formula that indicates the simplest whole number ratio of all the atoms in a molecule.
EXAMPLE : The empirical formula expresses the simplest whole number ratio of the atoms in the element.
In this case, the empirical formula of glucose is CH2O that is ratio Carbon : Hydrogen : Oxygen is 6 : 12 : 6 which is written in a simpler way as 1 : 2 : 1 hence the empirical formula of glucose is CH2O
Therefore the answer is molecular formula
hope this gives a better understanding , if you have any suggestions please let me know
