A sample containing a mixture of SrCl2·6H2O (MW = 266.62 g/mol) and CsCl (MW = 168.36 g/mol) originally weighs 1.9715 g. Upon heating the sample to 320 °C, the waters of hydration are driven off SrCl2·6H2O, leaving the anhydrous SrCl2. After cooling the sample in a desiccator, it has a mass of 1.6811 g. Calculate the weight percent of Sr, Cs, and Cl in the original sample. 1) wt% Sr 2) wt% Cs 3) wt% Cl
