    we will study is called copper chloride hydrate. We first drive out the water‚ which is called hydration. This occurs if we gently heat the sample to a little over 100*C. The compound formed is anhydrous (no water) copper chloride. If we subtract its mass from that hydrate‚ we can determine the mass of the water that was driven off‚ and using the molar mass of water‚ find the number of moles of H2O that were in the sample. Next‚ we need to the find either the mass of copper of chlorine in the anhydrous
