What is a molecular formula?

Answer 1

The full formula of a molecule. It states how many of each element in the molecule.

In a molecular formula, it states the total number of atoms of each element in a molecule.

For example, the molecular formula of glucose is #C_6H_12O_6#, and we do not simplify it into #CH_2O#.

And for each compound, they all have a molecular formula, but some can be similar, and those are called isomers, which are common in organic chemistry.

Mixtures do not have a single molecular formula, as they are made of many different compounds.

By displaying the actual numbers of each type of atom present in a molecule, a molecular formula represents a molecule and provides information about the types and numbers of atoms present in a compound, as well as the molecule's elemental composition.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
