Solution

The correct option is D $44$ g
The molecular weights of $C a C O_{3}$ and $C O_{2}$ are 100 g/mol and 44 g/mol respectively.
The balanced chemical equation is
$C a C O_{3} + 2 H C l \to C a C l_{2} + H_{2} O + C O_{2}$
Thus 1 mole (100 g) of $C a C O_{3}$ produces 1 mole (44 g) of $C O_{2}$ .
Hence 44 grams of $C O_{2}$ are produced by the complete reaction of 100 g $C a C O_{3}$ with excess $H C l$ .
