units for concentration

Concentration Units | Chemistry [Master]

Molarity (M) indicates the number of moles of solute per liter of solution (moles/Liter) and is one of the most common units used to measure the concentration of a solution. Molarity can be used to calculate the volume of solvent or the amount of solute.

The SI unit for molar concentration is mol/m 3. However, mol/L is a more common unit for molarity. A solution that contains 1 mole of solute per 1 liter of solution (1 mol/L) is called “one Molar” or 1 M. The unit mol/L can be converted to mol/m 3 using the following equation: 1 mol/L = 1 mol/dm 3 = 1 mol dm −3 = 1 M = 1000 mol/m 3 ...
