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

Calculate the concentration of hydrogen chloride in g per dm3

Respuesta :

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

Further explanation

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 :

[tex]\tt =\dfrac{3.2~g}{50~cm^3}=0.064~g/cm^3[/tex]

For the concentration of Hydrogen chloride in g per dm³ :

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

The concentration of hydrogen chloride will be "64 g/dm³".

According to the question,

Hydrochloric acid's solution contains "3.2 g" Hydrogen chloride in "50 cm³", then

The concentration will be:

= [tex]\frac{3.2}{50}[/tex]

= [tex]0.064 \ g/cm^3[/tex]

By converting "[tex]g/cm^3[/tex]" into "[tex]g/dm^3[/tex]", we get

= [tex]0.064\times \frac{1000 \ cm^3}{dm^3}[/tex]

= [tex]64 \ g/dm^3[/tex]

Thus the approach above is right.
