10 g of sample of mixture of CaCl(2) and...

10 g of sample of mixture of `CaCl_(2)` and NaCl are 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 `CaCl_(2)` in the original mixture is

A

0.321

B

0.162

C

0.218

D

0.12

Text Solution

Verified by Experts

a) `CaCl_(2) + NaCl = 10g`
Let, weight of `CaCl_(2)` = xg
`CaCl_(2) to CaCO_(3) to CaO`
Moleof CaO = `(1.62)/(56) rArr x/111 = 1.62/56 x = 3.21g`
`%` of `CaCl_(2)` = (3.21/10 x 100) = 32.1%`

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?

A 10 g sample of a mixture of calcium chloride and sodium chloride is treated with Na_(2)CO_(3) to precipitate calcium as calcium carbonate. This CaCO_(3) is heated to convert all the calcium to CaO and the final mass of CaO IS 1.12 gm. Calculate % by mass of NaCl in the original mixture.
