3. The mass percent of water in a hydrate of MnCl2 is 36.41%. What is the formula of the hydrate? A hydrated compound has analysis of 18.29% Ca, 32.37% Cl, and 49.34% H,O, 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. 6. A student had a sample of BaCl 2H,O. He heated a sample until the mass did not change. From this data, calculate the the percentage of BaCl, in the original sample. Mass of crucible + cover = 26.39 g Mass of crucible+ cover+ unknown sample 28.20 g Mass of crucible + cover + residue = 28.03 g
