How do you determine the molecular formula from a structural formula?

You determine the molecular formula from a structural formula by counting the number of each type of atom in the structure.

The molecular formula of a compound provides information about the type and number of atoms that make up the compound. To determine the molecular formula from a structural formula, you need to count the number of each type of atom present in the structure. The structural formula is a graphical representation of the molecular structure, showing how the atoms are arranged and bonded together.

Start by identifying the different types of atoms in the structure. These could be elements like carbon (C), hydrogen (H), oxygen (O), nitrogen (N), and so on. Then, count the number of each type of atom. For example, if you have a structure with six carbon atoms, twelve hydrogen atoms, and six oxygen atoms, the molecular formula would be C6H12O6.

It's important to remember that the molecular formula does not provide information about the arrangement of atoms. It only tells you what atoms are present and in what quantities. The structural formula, on the other hand, gives you a detailed picture of the molecule's structure, including which atoms are bonded to which and how they are arranged in space.

In summary, to determine the molecular formula from a structural formula, you need to identify and count the number of each type of atom in the structure. This will give you the molecular formula, which tells you the type and quantity of atoms in the compound.
