What is the unknown ionic compound molecular formula?

You can only have an empirical formula for an ionic substance, as it exists as a giant lattice. To speak of a molecular formula is a contradiction in terms, as ionic substances have no molecules. However I suspect you are after 'the formula to use in an equation ', and this is the same as the empirical formula.

Explanation:

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
