Homework Equations

The Attempt at a Solution

i was told to divide the percentages by the total molecular mass... makes no sense, they are looking for the hydrate formula and don't know how to do this

Try to solve assuming it it just the elemental analysis with an "element" X of molar mass 18.02 and constituting 14.24% of the substance.
