Liquid nitrogen Wikipedia

Liquid nitrogen is a diatomic liquid, which means that the diatomic character of the covalent N bonding in N 2 gas is retained after liquefaction. The temperature of liquid nitrogen can readily be reduced to its freezing point 63 K (−210 °C; −346 °F) by placing it in a vacuum chamber pumped by a vacuum pump.

Molecular weight of Nitrogen Convert Units

When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight.
