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...
