what is specific gravity of liquid nitrogen
Answered by The Community. Making the world better, one answer at a time. Liquid nitrogen (LN2) at atmospheric pressure and at its boiling point has a specific gravity of 0.808 (water = 1) or a density of 0.808 g/mL = 0.808 kg/L = 808 kg/m3 = 1.7813 lb/L = 50.44 lb/ft3 = 6.743 lb/US Gallon.
