3. a. If "Epsom salt", MgSO4. xH₂O, is heated to 250 ° C, all the water of hydration is lost. Write the chemical equation that represents this process. (The coefficient for the water will be X since you don't know the formula for the hydrate.) b. On heating a 1.687 g sample of the hydrate, 0.824 g of Mg SO4 remains. How many molecules of water occur per formula unit of MgSO4. Write the complete formula of the hydrate and state the complete name.
