How to Calculate and Solve for the Number of Moles, Volume and Molar Concentration in Chemistry | Nickzom Calculator

The image above represents the molar concentration.

To compute the molar concentration of a substance, two essential parameters are needed and these parameters are number of moles (n) and volume (V).

The formula for calculating the molar concentration:

c = nV

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

c = nV
c = 32120
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

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

V = n / c
V = 44 / 14
V = 0.318

Therefore, the volume is 0.318.
