There are many ways to express the concentration of a solution. Following are some of the basic stoichiometric formulae for calculating concentration of a solution.
Molarity[]
Molarity is a measure of concentration for solutions. The molarity of a solution is equal to the number of moles of solute divided by the number of Litres of solution. It is denoted by the letter 'M' in uppercase.
Mathematical Expression[]
Mathematically, ,
- Where, n = number of moles of solute; VL = volume in litres.
Molality[]
Molality is a measure of concentration calculated by dividing the number of moles of solute by the number of kilograms of solvent. Mathematically,
Normality[]
Normality is a measure of concentration calculated by dividing the number of gram equivalent of solute by the Volume of solvent in litres. It is denoted by the letter 'N'.
There's a relation between Normality and morality which is given by: N = xM; x = x-factor
