The Normality is defined as the number of gram equivalent of the solute dissolved per litre of the solution.
Contents
- Normality is denoted by N.
- Unit of Normality gram equivalent L-1
Formula :
N = Normality
n = number of Mole of solute
V = Volume of solution in litre
- If the volume of solution given in mL that the formula will be following.
