Reference no: EM132362967

A 1.1000 gram hydrate sample chosen from Na2CO3·10H2O, AlCl3·6H2O, MgCl2·6H2O and BaCl2·2H2O was heated and found to lose 0.4919 gram of H2O. (1) Show the calculation of the % H2O in the unknown hydrate sample. (2) Show the calculation of the % H2O in each of the hydrate compounds and identify the unknown hydrate from the list.

Atomic weights: H = 1.008, O = 16.00. MWs: Na2CO3·10H2O = 286.15, AlCl3·6H2O = 241.43, MgCl2·6H2O = 203.301 and BaCl2·2H2O = 244.462
