For converting a solution if 100 ml KCl of 0.4 M concentration into a solution of KCl 0.05 M concentration. The quantity of water added is

A

900 mL

B

700 mL

C

500 mL

D

300 mL

Text Solution

Verified by Experts

The correct Answer is:
B
We know that, `M_(1)V_(1)=M_(2)V_(2)`
`0.05xxV_(1)=0.4xx100`
`thereforeV_(1)=(0.4xx100)/(0.05)=800`
`V_(2)-V_(1)=800-100implies700mL`.
