1. Give the formula or the name of the following hydrated salts:a. cobalt(II) chloride hexahydrate b. iron(II) sulfate heptahydratec. CaCl2 x 2H2Od. Cu(NO3)2 x 3H2O 2. The mass percent of water in a hydrate of MnCl2 is 36.41%. What is the formula of the hydrate?3. A hydrated compound has analysis of 18.29% Ca, 32.37% Cl,and 49.34% H2O. What is its formula?4. A 4.00 g sample of a hydrate of nickel(III) bromide losses 0.793 g of water when heated. Determine the percentage of water in the hydrate and the formula of the hydrate.5. A student has a sample of BaCl2 x 2H2O. He heated a sample until the mass did not change. From this data, calculate the percentage of BaCl2 in the original sample.Mass of crucible + cover = 26.39 gMass of crucible + cover + unknown sample = 28.20 gMass of crucible + cover + residue = 28.03 g
