A sample of a mixture of \( \mathrm{CaCl}_{2} \) and \( \mathrm{NaCl} \) weighing \( 4.44 \) \( \mathrm{g} \) was treated to precipitate all the \( \mathrm{Ca} \) as \( \mathrm{CaCO}_{3} \), which was then heated and quantitatively converted to \( 1.12 \mathrm{~g} \) of \( \mathrm{CaO} \). (At . wt. \( \mathrm{Ca}=40, \mathrm{Na}=23, \mathrm{Cl}=35.5 \) )
(A) Mixture contains \( 50 \% \mathrm{NaCl} \)
(B) Mixture contains \( 60 \% \mathrm{CaCl}_{2} \)
(C) Mass of \( \mathrm{CaCl}_{2} \) is \( 2.22 \mathrm{~g} \)
(D) Mass of \( \mathrm{CaCl}_{2} 1.11 \mathrm{~g} \)
