Formula for Molar Concentration: Chemistry Notes With Example

Molar concentration

 describes the concentration of a solute in a solution.

It can be expressed by the formula :

Let us consider an illustration of the molar concentration of NaOH between HCl and NaOH.

The above chemical reaction could be represented as:

For an acid, the number of moles of HCl is equal to:

The mole ratio of NaOH and HCl is 1:1.

Hence the number of moles present in NaOH is also equal to:

Since the volume of aqueous NaOH is 25 cm3, let us convert it into dm3.

Now by using the molar concentration formula let us calculate the molar concentration of NaOH.

Thus, the molar concentration of NaOH is:
