Question

in case of ionic substance a more appropriate term is the formula of weight rather than molecular weight why​

Answer 1

Answer:

Because Ionic substances do not form a molecule

Explanation

Ionic substances do not form a molecule because it has two species of different charges. For instance : Nacl is a ionic substance, It has two different species that is Sodium , being positive and chlorine being negative. The two ions exist independently.

Ionic substances do not form molecule but has two different ions of different charges making them electrically neutral.

Thus, Formula weight is appropriate than molecular weight.
