- Percent Concentration
Molar volumetric concentration

Mole equivalent concentration

- Concentrations:

Mass fraction (also called percentage concentration):

C = m1 / m

where:

m1 mass of solute, g (kg);

m total solution mass, g (kg).

The percentage by weight of the component, m%

m% = (mi / # 931; mi) * 100Molarity (molar volume concentration) is the amount of dissolved substance (number of moles) per unit volume of solution.

C (M) = n / V

where:

n amount of solute, mole;

V total volume of solution, l.The normal concentration (mole equivalent concentration)

C (N) = z / V

where:

V total volume of solution, l;

z the number of equivalents (the number of equivalents of the dissolved substance).
