10 mL of mixture containing carbon monoxide and nitrogen required 7mL, oxygen to form CO_(2) and NO, on combustion The volume of N_(2) in the mixture will be:

Answer»

7/2mL
17/2mL
4mL
7mL

Solution :`CO(g)+(1)/(2)O_(2)(g)rarrCO_(2)(g)`
`N_(2)(g)+O_(2)(g)rarr2NO(g)`
`X+y=10`
`(x)/(2)+y=7`
Solving eqs, i and II,
`x=6` and y=4
