10ml of compound containing 'N' and 'O' ...

`10ml` of compound containing 'N' and 'O' is mixed with `30ml` of `H_(2)` to produce `H_(2)O (l)` and `10ml` of `N_(2)(g)`. Molecular formula of compound if both reactants completely, is

A

`N_(2)O`

B

`NO_(2)`

C

`N_(2)O_(3)`

D

`N_(2)O_(5)`

Text Solution

Verified by Experts

The correct Answer is:
C
`C_(6)H_(5)OH(g)+7O_(2)(g)rarr6CO_(2)(g)+3H_(2)O(l)`
`V_(i)=30ml "excess"`
`V_(f)=0 " "("excess"-210) " "180`
`V_(i)=30+ "excess"`
`V_(f)=(180 + "excess"-210)`
`V_("cont")=60ml`
