5.82g of a Hydrate is taken. If 62.9% of H2O is contained in the Hydrate what is the mass of the anhydrous salt?

so far i got 62.9% and 37.1% and i was thinking about getting H2O in grams but i dont know how

Well, if you multiply 0.371 by 5.82, I believe that would give you the mass of the anhydrous salt since 0.629 x 5.82 is the mass of the water contained in the hydrate.
