How to express concentration in solution?
For the concentration
of solution, there are plenty of methods to illustrate it. In general, in our
daily lives, people prefer to use mass fraction of solute to show the
concentration of solution, because this method is convenient. However, for
chemistry studying, people prefer to use molar mass fraction of solute, because
this method is easy to make any chemical calculations.
Actually, in
chemical calculation, there are four methods to compute the concentrations. 1. Mass concentration: The mass concentration is defined
as the mass of a constituent divided by the volume of the mixture V. 2. Molar
concentration: The molar concentration is defined as the amount of a
constituent in moles divided by the volume of the mixture V. 3. Number
concentration: The number concentration is defined as the number of entities of
a constituent in a mixture divided by the volume of the mixture V. 4. Volume
concentration: The volume concentration is defined as the volume of a
constituent divided by the volume of the mixture V.
