A) \[400\text{ }c{{m}^{3}}\]
B) \[~500\text{ }c{{m}^{3}}\]
C) \[~450\text{ }c{{m}^{3}}\]
D) \[~100\text{ }c{{m}^{3}}\]
Correct Answer: A
Solution :
To get decinormal concentration, suppose the total volume of water\[=x\] \[\therefore \] \[100\,c{{m}^{3}}\times 0.5\,N=x+0.1\,N\] \[\therefore \] \[x=\frac{100\times 0.5}{0.1}=500\,c{{m}^{3}}\] Therefore the volume of water added \[=\text{Total}\,\text{volume}\,-100\,c{{m}^{3}}\] \[=500-100=400\,c{{m}^{3}}\]You need to login to perform this action.
