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 · x h2o, where x indicates the number of moles of h2o per mole of mgso4. when 3.484 g of this hydrate is heated to 250°c, all the water of hydration is lost, leaving 1.701 g of mgso4. what is the value of x?
