How to Calculate Molar Concentration?

These are the simple steps to calculate the solution molar concentration easily.

  • Find the volume, number of moles in a solution.
  • Divide the number of moles by the volume to get the molar concentration.

Molar Concentration Definition

Molar concentration is the amount of concentration of a substance in the solution. It is the most convenient way of describing the solute concentration in a solution. It can also be defined as the amount of substance per unit volume.

Molarity is the total number of moles of solute dissolved per litre of solution. The molar concentration can be obtained by dividing the number of moles by the volume of the solution.

Molar Concentration Formula

Molar concentration formula is given by

Molar concentrtaion = Number of moles / Volume of Solution

Example:

Question: Find the molar concentration of NaOH for the reaction between HCl and NaOH.

Answer:

The balanced chemical equation is

HCl + NaOH → NaCl + H2O

For an acid,

Number of moles of HCl = (35.0 / 1000 dm3) × 0.250 mol dm-3

= 8.75 x 10-3 mol

The mole ratio of NaOH : HCl = 1 : 1

The amount of NaOH = 8.75 x 10-3 mol

52 cm3 = 25 x 10-3 dm3

Molar concentrtaion = Number of moles / Volume of Solution

= 8.75 x 10-3/25 x 10-3

= 0.35

Therefore, molar concentration of NaOH = 0.35 mol dm-3
