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

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:

=

=

By converting "" into "", we get

=

=

Thus the approach above is right.

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

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 :

For the concentration of Hydrogen chloride in g per dm³ :

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.

the answers would be
