Hello Candidate,
The number of gram equivalents of solute is equal to the weight of solute added divided by the molar mass of solute or salt solution. The molar mass of NaCl is equal to 58.5, so the gram equivalent of solute is equal to 58.5/58.5= 1.
The volume of solvent is equal to 500ml or can be expressed as 0.5 litres. So, the formula of normality is equal to gram equivalent of solute / the volume of solvent in litres which is equal to 1/0.5= 2 Normal
Hope you found it helpful. If you have any further queries feel free to post it here!!
