Solution Preview

Non-ionic compounds are covalent compounds. As such, the molecular formulas and empirical formulas can be different. However, with ionic compounds, the empirical formula is the same as the molecular formula all the time.

An empirical formula is kind of like the "lowest common chemical denominator" of a compound. That means that the true molecular ...
