5mL of `N HCI, 20 mL` of `N//2 H_(2)SO_(4)` and 30 mL of `N//3 HNO_(3)` are mixed together and volume made to one litre. The normality of the resulting solution is

A

N/5

B

N/10

C

N/20

D

N/40

Text Solution

Verified by Experts

The correct Answer is:
d
`N_(1)V_(1)+N_(2)V_(2)+N_(3)V_(3)=N_(4)V_(4)`
`1xx5+1//2xx20_//3xx30=N_(4)xx1000`
`5+10+10=N_(4)xx1000`
`N_(4)=25/1000=1/40`
