Question

given that one mole of nitrogen at NTP occupies 22.4 litre the density if nitrogen is?

Answer 1

Hello Dear.

Given ⇒

Volume of the Nitrogen at N.T.P. (Normal Temperature and Pressure) = 22.4 liter.

We know, Nitrogen is the Diatomic gas,

∴ Molar Mass of the Nitrogen = 28 g/mole.
[∵ 14 × 2 = 28]


∵ Density = Mass/Volume 
∴ Density = 28/22.4
  Density of the Nitrogen = 1.25 g/liter.


Hence, the Density of the Nitrogen at N.T.P. (Normal Temperature and Pressure) is 1.25 g/l.


Hope it helps..

Answer 2

Answer:

THE ANSWER IS : - 1.25g/l

Explanation:

see, guys nitrogen is a diatomic gas ,

therefore the total MASS will be:-14*2 = 28..............(i)

now the given VOLUME at NTP is 22.4........................(ii)

as we know that , DENSITY = MASS/VOLUME....

so,  by (i) and (ii),we got the density as:-

DENSITY = 28/22.4........

that will be = 1.25g/l...
