Solution

The correct option is C $0.9375$ g
1000ml of 0.75 M HCl = 0.75 mol

So, 25 ml of HCl will contain HCl = $0.75 \times 25 / 1000$ = 0.01875
2 mol of HCl reacts with 1 mol of $C a C O_{3}$

So, 0.01875 mol of HCl will react with $\frac{1}{2}$ $\times$ 0.01875 = 0.009375 mol

Molar mass of $C a C O_{3}$ = 100 g

Hence, the mass of 0.009375 mol of $C a C O_{3}$ = no. of moles $\times$ molar mass
= $0.009375$ $\times$ $100$
= $0.9375$ g
Hence, the correct option is $C$ .
