The volumes of `4N HCI` and `10 N HCI` required to make 1 litre of `6N HCI` are

Options

A. 0.75 litre of 10 HCl and 0.25 litre of 4 N HCl
B. 0.25 litreof 4 N HCl and0.75 litre of 10 N HCl
C. 0.67 litre of 4 N HCl and 0.33 litre of10 N HCl
D. 0.80 litre of 4 N HCl and 0.20 litre of 10 N HCl

Answer

C

Explanation

`N_(mix)=( N_(1)V_(1)+ N_(2)V_(2))/(V_(mix))`
Value of`N_(mix)` for (a) is 8.5 N, for ( b) 8 N ,for ( c ) is 5.98 N and for ( d) is 5.2 N . Resulting mix. Is 6 N`~~ 5.98 N `.
