A Gasaeous compound of Nitrogen and Hydrogen contains `12.5%` by weight of Hydrogen. The density of the compound relative to Hydrogen is 16, the molecular formula of the compound is

A

`NH_(2)`

B

`NH_(3)`

C

`NH_(4)`

D

`N_(2)H_(4)`

Text Solution

Verified by Experts

The correct Answer is:
D
`%H 12.5 (12.5)/(1) = 12.5`
`%N 87.5 (87.5)/(14) = 6.25 :. E.F = NH_(2)`
V.D of compound =16`
`( :'` given in question)
`M.F. Wt = 16 xx 2 = 32`
