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?

3.68g of a mixture of calcium carbonate and magnesium carbonate when heated strongly leaves 1.92g of a white residue. Find the percentage composition of the 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 sample of a mixture of CaCl_(2) and NaCl weighing 4.44 gm was treated to precipatate all the Ca as CaCo_(3) , which was then heated and quantitatively converted to 1.12 g of CaO. Choose the correct statements. (Atomic weight :Ca=40=23, Cl =35.5)
