Normality Formula – Equation and Problem Solved with Example
Normality Formula is used to represent the concentration of a solution or it is defined as the total weight of solute dissolved within a liter of solution. This would be easy to calculate the Normality of an equation when you know the atomic masse and the volume of the composition.
When the composition is same for the solute or solvent, then the solution is usually saturated. Here is the Normality Formula for an equation where Molarity is divided by the total number of equivalents.
Normality is not used frequently when compared to other concentration measuring solutions like Molarity or Molality. Here, you need to check the gram equivalent weight first and it is usually checked by the total number of ions that reacts and it could change as well based on the reaction.
The reason is gram equivalent weight is not consistent and it may create confusion, so prefer using other concentration values. In the Normality Formula, we have been used one term Molarity that is defined as total number of moles per liter of solution. Here, is the formula to molarity of a solution.
Molarity = moles of solute/liters of solution
The other popular term to measure concentration is Molality (m) and it isdefined as the number of moles of solute per kilogram of solvent.
Molality = moles of solute/kilograms of solvent
You have to be extra cautious when using Molarity or molality and they should not be used interchangeably.
