... Normality (CN). Normality is defined as the number of moles of the equivalent of a solute (neq) in 1 liter of a solution; that is, CN = neq (solute) / V (solution). Thus, normality has the units of mol/L or N. In chemical reactions the molar ratio of reacting substances is not always 1:1. It is dete ...
