Question

4. For ionic compounds, why is it reasonable to use the term 'formula weight rather than ‘molecular weight'?​

Answer 1

Answer:

because

becauseSome compounds do not exist as individual molecules. For example, there is no such thing as a molecule of sodium chloride. That's why it is appropriate to use the term formula weight for this type of compound. However, some compounds do exist as individual molecules. For example, water,carbon-dioxide etc. So it is appropriate to use the term molecular weight for it.

Answer 2

Answer:

Molecules are not present in ionic substances. Only ions are present. The formula of an ionic substance represents the simpler ratio of ions in one mole of crystal. Hence a more appropriate term is 'formula weight'.
