Epsom salts, a strong laxative used in veterinary medicine, is a hydrate, which means that a certain number of water molecules are included in the solid structure. The formula for Epsom salts can be written as MgSO4⋅xH2OMgSO4⋅xH2O, where xx indicates the number of moles of H2OH2O per mole of MgSO4MgSO4. When 7.592 gg of this hydrate is heated to 250 ∘C∘C, all the water of hydration is lost, leaving 3.708 gg of MgSO4MgSO4. What is the value of x?
