The answer is 0 if im right
The molecular formula shows the exact number of molecules. Therefor, the empirical formula is the simplest formula of the molecular formula
Answer: Anna stated that ionic compounds have high melting point and low boiling point. The error in the statement is that ionic compound have low boiling point, instead ionic compounds have high boiling point, because in an ionic compound, the force of attraction working between two ions is very strong and hence the bonds present are very strong, and a lot of energy is needed to break them
