Answer:

The density of #N_2# is 1.250625 g/L
or simply 1.25 g/L

Explanation:

At STP,

The molecular mass of #N_2# is 28.014 g/mol.

The volume of#N_2# is 22.4L.

Density of #N_2# =Molecular mass of #N_2# )/Volume of #N_2#

#rArr# #(28.014)/(22.4)# g/L

= 1.2506255 g/L

                                              or simply 1.25 g/L.

Answer:

First - be aware that it DOESN'T.
#(28g)/(22.4L) = 1.25 g/L#

Explanation:

It only occupies that volume at STP, not NTP. It is unnecessary given the terms of the terms of the problem in any case.
A mole of nitrogen (#N_2#) has a mass of 28 grams/mole. Density is mass per unit volume, so the density is simply:

#(28g)/(22.4L) = 1.25 g/L#
