A sampe of `NH_(3)` occupies 5.6 litres at 2 atm & `273^(@)C`. Which of the following options are correct ?A. Sample contains `3/4` gm atoms of hydrogenB. Sample contains 10.5 gm of nitrogenC. Volume of the sample at NTP Will be same as volume occupied by 12 gm of ozone gas at NTPD. Density of the above gaseous sample at 3 atm pressure & 300 K is equal to 2.07 gm/ml. |

Answer» Correct Answer - AC `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. |
