Relation between Molarity and Normality
Two significant and usually utilized terms in chemistry are normality and molarity. They are employed to denote a substance’s quantitative measurement. It is a chemical unit of concentration, similar to normality. The number of moles of solute per liter of solution is known as molarity. It also goes by the name “molar concentration.” Molarity, such as dissociation or equilibrium constants, is frequently utilized in the determination of pH.
Normality (N) = Molarity × (Molar mass) / (Equivalent mass)
Molarity – Definition, Formula and Solved Examples
Molarity is defined as total number of moles of solute per litre of solution. It is represented by M. In chemistry, the molarity is one of the concentration units. The concentration of solutions can be expressed more effectively using measurements based on moles. The SI unit of Molarity is Mole.
A mole is an SI unit that measures the amount of a substance, where the amount of a substance is a measurement of the number of its elementary entities present in an object or sample. According to the definition, a mole contains exactly 6.022 × 1023 elementary entities, where 6.022 × 1023 is called Avogadro’s number (NA). Molarity is used to measure the concentration of a solution, where a concentrated solution is a solution with more solute and less solvent.
