    At STP, the volume of one mole of any gas is taken to be 22,400 ml. So, at STP, one mole = 14 gm Nitrogen will be 22,400 ml.

    SO now, this is easy to get the answer:

    14 gm = 22,400 ml

    so density will be (14/22400) gm/ml = 0.625 gm/ltr or 0.625 kg/m3.

    all the best.. :)

    Well, for any ideal gas at STP 1 mol = 22.4 L. Since the molar mass of N2 is 28.0 g/mol, you have 28.0 g/22.4 L = 1.25 g/L
