http://websites.umich.edu/~chem241/lecture8.pdf WebMolarity(M) is a measure of concentration in terms of the mole and is moles of a substance per liter (mol/L) of solution. 1 M solution of NaCl would be 58.44 g/L of NaCl. An equivalent is 1 mol of reactive species, whether it is an H+of acid–base reactions, an electron of reduction–oxidation reactions, or some other unit.
