Given that one mole of N2 at NTP occupies 22.4 litre the density of N2 is...

Hey Rahul!!

At NTP, 1 mole of N2 has volume = 22.4 litre  =  22.4 x 1000 cm3 =  22400 cm3
Mass of 1 mole of N2 = 28g
Density = Mass/Volume
            = 28 / 22400
           = 0.00125 g cm-3
          = 1.25 x 10-3 g cm-3


Hope you find the answer helpful.
