In which ratio of volumes 0.4 M HCl and ...

In which ratio of volumes 0.4 M HCl and 0.9 M HCl are to be mixed such that the concentration of the resultant solution becomes 0.7 M ?

A

`4 : 9`

B

`2 : 3`

C

`3 : 2`

D

`1 : 1`

Text Solution

Verified by Experts

The correct Answer is:
B
Let the volume ratio = x : y a/c to question
`0.7=(0.4x+0.9y)/(x+y)implies0.7x+0.7y=0.4x+0.9y`
`implies0.3x=0.2yimplies(x)/(y)=(0.2)/(0.3)implies(x)/(y)=2:3`
