Suppose you want to know the formula of a hydrate of magnesium sulfate. If you heat 1.998 g of the hydrate until all of the water is vaporized, the mass of anhydrous MgSO4 is 0.976 g. What is the formula of the hydrate, i.e. what is the value of x in MgSO4.xH2O? (The formula weight of anhydrous magnesium sulfate is 120.37 g/mol)

    CHM 010 On-Line Lab, Formula of a Hydrate PURPOSE: To determine the formula of Cuso..x H20. In other words, to determine the value of "X". PROCEDURE: When copper(II) sulfate x hydrate, a blue crystalline solid containing embedded water molecules (called a hydrate), is heated in air, it loses the water molecules and the blue solid is transformed to a white anhydrous (no water) crystal known as anhydrous copper(II) sulfate. The "x" represents a whole number of water molecules attached to...

    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⋅xH2O, where x indicates the number of moles of H2O per mole of MgSO4. When 4.555 g of this hydrate is heated to 250 ∘C, all the water of hydration is lost, leaving 2.225 g of MgSO4. What is the value of x?
