`100ml` of `2.45 % (w//v) H_(2)SO_(4)` solution is mixed with `200ml` of `7% (w//w) H_(2)SO_(4)` solution `("density" = 1.4 gm//ml)` and the mixture is diluted to `500ml`. What is the molarity of the diluted solution ?

A

`0.25 M`

B

`1.0 M`

C

`0.75 M`

D

`0.45 M`

Text Solution

Verified by Experts

The correct Answer is:
D
`M_(1)V_(1)+M_(2)V_(2)=M_(f)V_(f)`
`(100xx(2.45)/(100))/(95)+(200xx(7)/(100))/(98)=500xxM_(f)`
`M_(f)=0.45 M`
