If 250 ml of 0.25 M NaCl solution is diluted with water to voluem of 500 ml, the new concentration of the solution is :

A

0.167 M

B

0.125 M

C

0.50 M

D

0.0625 M

Text Solution

Verified by Experts

The correct Answer is:
B
`M_(1)V_(1)=M_(2)V_(2)`
`0.25 M xx 250 ml M_(2)xx500ml`
`:.M_(2)=(0.25xx250)/(500)=0.125M`
