A solution of hydrochloric acid contains 3.2 g of hydrogen chloride in 50 cm3

Harrizon [31]

The concentration of Hydrogen chloride in g per dm³ = 64 g/dm³

<h3>Further explanation</h3>

The concentration of a substance can be expressed in several quantities such as moles, percent (%) weight / volume,), molarity, molality, parts per million (ppm) or mole fraction. The concentration shows the amount of solute in a unit of the amount of solvent

A solution of hydrochloric acid contains 3.2 g of hydrogen chloride in 50 cm³, so the concentration :

$\tt =\dfrac{3.2~g}{50~cm^3}=0.064~g/cm^3$

For the concentration of Hydrogen chloride in g per dm³ :

$\tt =0.064\dfrac{g}{cm^3}\times \dfrac{1000~cm^3}{dm^3}\\\\=64~g/dm^3$
