1. 5.00 grams of an unknown iron nitrate hydrate (Fex(NO3)y ZH2O) was heated to remove the water. The resulting anhydrous iron nitrate had a mass of 2.99g. The resulting solid was dissolved in water and allowed to react with aluminum to create solid iron through an oxidation-reduction process. The iron was isolated, dried, and had a mass of 0.690g. a. Calculate the mass of water lost during heating b. Calculate mass of nitrate in the original unknown sample Mass of water lost: Mass of nitrate in the unknown sample: c. Calculate the moles of water, iron, and nitrate in the unknown sample Moles of water_ Moles of iron Moles of nitrate d. What is the empirical formula for the unknown iron nitrate hydrate?
