0.45 N & 0.6 N NaOH solution are mixed in 2:1 by volume. The amount of solute present in 1 lit of this solution is

A

0.5 gm

B

25 gm

C

20 gm

D

5 g

Text Solution

Verified by Experts

The correct Answer is:
C
`(N_(1)V_(1)+N_(2)V_(2))/(V_(1)+V_(2))=N`
`N=(0.45xx2+0.6xx1)/(3)=0.5N`
implies 0.5 moles in 1 lit. = 20g
