The volume of 10N and 4N HCL requied to make 1L of 7N HCl are

A

0.50 L of 10 N HCl and 0.50 L of 4N HCl

B

0.60 L of 10 N HCl and 0.40 L of 4N HCl

C

0.80 L of 10N HCl and 0.20 L of 4N HCl

D

0.75 L of 10 N HCl and 0.25 L of 4N HCl

Text Solution

Verified by Experts

The correct Answer is:
A
Let V litre of 10 N HCl be mixed with `(1-V)` litre of 4N HCl to give `(V+1-V)L=1` of 7N HCl
`N_(1)V_(1)+N_(2)V_(2)=NV`
`10V+4(1-V)=7xx1`
`10V+4-4V=7`
`6V=3impliesV=0.5L`
Volume of `10 N HCl =0.5L`
Volume of `4 N HCl =0.5 L`
