    \[100\,g\] \[CaC{{O}_{3}}\] is treated with \[1\text{ }L\] of \[1\text{ NHCl,}\] what would be the weight of \[C{{O}_{2}}\] liberated after the completion of the reaction?

    A)  \[55\,g\]                      

    B)  \[11\,g\]

    C)  \[22\,g\]                      

    D)  \[44\,g\]

    Correct Answer: A

    Solution :

    \[\underset{(20+12+48=80)}{\mathop{CaC{{O}_{3}}}}\,\xrightarrow{{}}\underset{(12+32=44)}{\mathop{C{{O}_{2}}}}\,\] \[\because \]  \[80\,g\] \[CaC{{O}_{3}}\] produces \[=44\,C{{O}_{2}}\] \[\therefore \]  \[100\text{ }g\] \[CaC{{O}_{3}}\] produces \[=\frac{44}{80}\times 100=55g\]
