A) \[300\,\,c{{m}^{3}}\]
B) \[200\,\,c{{m}^{3}}\]
C) \[500\,\,c{{m}^{3}}\]
D) \[400\,\,c{{m}^{3}}\]
Correct Answer: C
Solution :
No. of millimoles of \[Ca{{(OH)}_{2}}=50\times 0.5=25\] No. of millimoles of \[CaC{{O}_{3}}=25\] No. of milliequivalents of \[CaC{{O}_{3}}=50\] \[\therefore \] Volume of \[0.1\,N\,HCl=\frac{50}{0.1}=500\,c{{m}^{3}}\]
