3. As shown in the table below, the general formula of barium chloride hydrate is BaCl2 nH20, where n is the number of water molecules. Complete the table, and calculate the theoretical percent water in the hydrate. Note that BaCl2 is not a hydrate; it is simply the anhydrous salt. BaCl2 BaCl2 H20 BaCl2 2H20 BaCl2 3H20 Sum of atomic masses of 208.23 208.23 anhydrous salt (BaCl2) Sum of atomic masses of 0 18.02 water (nH20) Sum of atomic masses of 208.23 244.26 the hydrate (Ba Cl 2 *n H2 O) (0/208.23) x 100%= 0% Percent water in hydrate (theoretical)
