The measurements of concentration is a method used to quantify the concentration of solutions. Such measurements include molarity, mass-volume percent, volume percent, and others.

Terminology

Solute: The material be dissolved.

Solvent:

The material used to dissolve solute.

Solution:

The liqued of solute and solvent.

Molarity

Molarity (denoted by M) equals the moles of the solute (denoted by M_solute) divided by the liters of solution (denoted by L_solution) after mixing.

\[M = \frac{M\_solute}{L\_solution}\]

Mass-volume Percent

For mass-volume(denoted by MV) percent, the mass of the solute(denoted by m_solute) is divided by the volume of the solution(denoted by L_solution).

\[MV = \frac{m\_solute}{L\_solution}\]

Volume Percent

Volume percent(denoted by VP) equals the quotient of the volume of the solute (denoted by v_solute) divided by the sum of the volumes of the solute and solvent(denoted by v_solvent).

\[VP = \frac{v\_solute}{v\_solvent + v\_solute}\]
