Molar concentration
also called molarity, amount concentration or substance concentration,
is a measure of the concentration of a solute in a solution, or of any chemical species,
in terms of amount of substance in a given volume.
A commonly used unit for molar concentration used in chemistry is mol/L.
A solution of concentration 1 mol/L is also denoted as 1 molar (1 M).
The molar concentration is defined as the amount of a constituent (in moles) divided by the volume of the mixture.
The molecular weight of the solute - for example, for NaCl is 22.99
(molecular weight of Na)+35.44 (molecular weight of Cl), 23.99+35.45 = 58.44, thus, molecular weight of NaCl = 58.44
