Molar concentration



Molar concentration (also called molarity, amount concentration or substance concentration) is a measure of the concentration of a chemical species, in particular of a solute in a solution, in terms of amount of substance per unit volume of solution. In chemistry, the most commonly used unit for molarity is the number of moles per litre, having the unit symbol mol/L. A solution with a concentration of 1 mol/L is said to be 1 molar, commonly designated as 1 M

Molar concentratione (M, Cm) – number of moles of a given chemical that contain 1 dm 3 solution.

The molar concentration is equal to the ratio of the number of moles of solute to the volume of the solution. The unit of molar concentration in the SI system is mol × m -3 , however, in the chemical literature mol × dm -3 = mol / dm 3 is commonly used. = mol / l, also saved as "M". To express low concentrations, units of mM, μM, nM etc. are also used. Determination of the solution as n-molar means that its molar concentration is n mol / dm 3 .

The molar concentration of substance X is written in square brackets [X]

$$ C_{m}=\frac{n}{V_{r}}=\frac{m_{s}}{MV_{r}} $$
where:
\( n \)– number of moles substances [mol],
\( m_{s} \)- mass of dissolved substance [g],
\( M \)- molar mass of dissolved substance [g/mol],
\( V_{r} \)- volume of the solution [dm3],

The molar concentration depends on the temperature, because the volume of the solution varies with the temperature.
