A 10.0 g sample of a mixture of CaCl_2 and NaCl is treated to precipitate all the calcium as calcium carbonate. Thus CaCO_3 is heated to convert all the Ca to CaO and the final mass of CaO is 1.62 g. What is the percentage by mass of CaCl_2 in the original mixture?

10 g of a sample of a mixture of CaCl_(2) and NaCl is treated to precipitate all the calcium as CaCO_(3) . This CaCO_(3) is heated to convert all the Ca to CaO and the final mass of CaO is 1.62 g.The percent by mass of CaCl_(2) in the origial mixture is

A mixture of sodium chloride(NaCl) and anhydrous sodium carbonate (Na_(2)CO_(3)) has a mole ratio, 2:1 . It is dissolved in water and treated with BaCl_(2) solution. The mass of BaCO_(3) precipitated is 197 gm. Calculate the mass (in gm) of NaCl in the mixture.

A mixture of CaCl_(2) and NaCl weighing 4.44 is treated with sodium carbonate solution to precipitate all the Ca^(2+) ions as calcium carbonate. The calcium carbonate so obtained is heated strongly to get 0.56 g of CaO . The percentage of NaCl in the mixture of (atomic mass of Ca=40) is
