To calculate the molar concentration of a substance, two essential parameters are needed and these parameters are the number of moles (n) and volume (V).
The formula for calculating the molar concentration:
c = n ⁄ V
Where;
c = Molar Concentration
n = Number of moles
V = Volume
Let’s solve an example;
Find the molar concentration when the number of moles is 32 with a volume of 120.
This implies that;
n = Number of moles = 32
V = Volume = 120
So, c = n ⁄ V
c = 32 ⁄ 120
c = 0.266
Therefore, the molar concentration is 0.266 mol/L.
Calculating the Number of Moles when Molar Concentration and Volume is Given
n = Vc
Where;
n = Number of moles
c = Molar Concentration
V = Volume
Let’s solve an example;
Find the number of moles when the molar concentration is 40 with a volume of 31.
This implies that;
c = molar concentration = 40
V = Volume = 31
That is, n = Vc
n = 31 x 40
n = 1240
Therefore, the Number of Moles is 1240 mol.

Calculating the Volume when Molar Concentration and Number of Moles is Given
V = n / c
Where;
V = Volume
n = Number of moles
c = Molar Concentration
Let’s solve an example;
Find the volume when the molar concentration is 14 with a number of moles of 44.
This implies that;
c = molar concentration = 14
n = Number of moles = 44
So, V = n / c
V = 44 / 14
V = 0.318
Therefore, the volume is 0.318.
