If 500 mL of a 5M solution is diluted to 1500 mL, what will be molarity of the solution obtained ?

A

1.5 M

B

1.66 M

C

0.017 M

D

1.59 M

Text Solution

Verified by Experts

The correct Answer is:
B
`M_(1)=5M`
`V_(1)=500mL`
`V_(2)=1500mL`
`M_(2)=M`
For dilution, a general formula is
`underset(("Before dilution"))(M_(1)V_(1))=underset(("After dilution"))(M_(2)V_(2))`
`500xx5M=1500xxM`
`M=(5)/(3)=1.66M`.
