Solution

The correct option is A 0.9375 g
Using morality, Number of moles are calculated for $1000 m l$ or $1 L$ of the solution.
$1000 m l$ contains $0.75 M H C l$
$H C l = 0.75$ mole.
Therefore, $25 m l$ of $0.75 M$ HCl will contains $H C l = \frac{0.75 \times 25}{1000} = 0.01875 m o l e$
$2$ moles of $H C l$ reacts with $= 1 m o l e$ of $C a C O_{3}$
Therefore,
$0.01875$ mole of $H C l$ will react with $= \frac{1 \times 0.01875}{2}$
$= 0.009375 m o l e$
Molar mass of $C a C O_{3} = 100 g$
Hence, the mass of $0.009375$ of $C a C O_{3} = n o . o f m o l e s \times m o l a r m a s s = 0.9375 g$
