    The decomposition of a certain mass of \[CaC{{O}_{3}}\] gave \[11.2\text{ }d{{m}^{3}}\]of \[C{{O}_{2}}\] gas at STP The mass of \[KOH\] required to completely neutralise the gas is:

    A)  \[56g\]          

    B)  \[28g\]

    C)  \[42g\]          

    D)  \[20g\]

    Correct Answer: B

    Solution :

    Weight of \[11.2\text{ }d{{m}^{3}}\]of  \[C{{O}_{2}}\]gas at \[STP=44/2\]\[=22g.\] \[\underset{56g}{\mathop{KOH}}\,+\underset{44g}{\mathop{C{{O}_{2}}}}\,\xrightarrow{{}}KHC{{O}_{3}}\] \[KOH\]required for complete neutralisation
