A sampe of `NH_(3)` occupies 5.6 litres at 2 atm & `273^(@)C`. Which of the following options are correct ?

Options

A. Sample contains `3/4` gm atoms of hydrogen
B. Sample contains 10.5 gm of nitrogen
C. Volume of the sample at NTP Will be same as volume occupied by 12 gm of ozone gas at NTP
D. Density of the above gaseous sample at 3 atm pressure & 300 K is equal to 2.07 gm/ml.

Answer

AC

Explanation

`n=(PV)/(RT)=(2xx5.6)/(0.0821xx546) =11.2/(2xx22.4) =1/4`
`NH_(3) to 1/4` mole
`toN to 1/4` mole or gm atoms
`to H to 3/4` mole or gm atoms
Mass of nitrongen `=14/4=3.5 gm`
`PM=dRT`
`d=(3xx17)/(0.0821xx300) =2.07 ` gm/Ltr.
