200 mL of water is added to 500 mL of 0.2 M solution. What is the molarity of the diluted solution ?

A

0.5010 M

B

0.2897 M

C

0.7093 M

D

0.1428 M

Text Solution

Verified by Experts

The correct Answer is:
D
`M_(1)V_(1)-=M_(2)V_(2)`
`0.2Mxx500-=M_(2)xx700`
`M_(2)=((0.2M)xx500)/(700)=0.1428M`
