How to Calculate and Solve for the Molar Concentration, Molar Mass and Mass Concentration in Chemistry | The Calculator Encyclopedia

The image above represents the mass concentration.

To compute for mass concentration, two essential parameters are needed and these are molar concentration (c) and molar mass (M).

ρ = c x M

Where;
ρ = mass concentration
c = molar concentration
M = molar mass

Let’s solve an example;
Find the mass concentration when the molar concentration is 24 and molar mass is 15.

This implies that;
c = molar concentration = 24
M = molar mass = 15

ρ = c x M
ρ = 24 x 15
ρ = 360

Therefore, the mass concentration is 360 Kg/dm³.

Calculating the Molar Concentration when the Mass concentration and Molar Mass.

c = ρ / M

Where;
c = molar concentration
ρ = mass concentration
M = molar mass

Let’s solve an example;
Find the molar concentration when the mass concentration is 120 with a molar mass of 40.

This implies that;
ρ = mass concentration = 120
M = molar mass = 40

c = ρ / M
c = 120 / 40
c = 3

Therefore, the molar concentration is 3 mol/L.

Calculating the Molar Mass when the Mass concentration and Molar Concentration .

M = ρ / c

Where;
M = molar mass
ρ = mass concentration
c = molar concentration

Let’s solve an example;
Find the molar mass when the mass concentration is 150 with a molar concentration of 30.

This implies that;
ρ = mass concentration = 150
c = molar concentration = 30

M = ρ / c
M = 150 / 30
M = 5

Therefore, the molar mass is 5 mol.
