Nitrous oxide, also known as N2O, has a molar mass of 44.0128g/mol. It has a melting point of -90.81 degrees Celsius, and a boiling point of -88.46 degrees Celsius. Nitrous oxide is colorless and has a slightly sweet Oder and is highly soluble in alcohol, ether, oils, and sulfuric acid. The density of N2O is 1.799 g/L at 25 degrees Celsius and standard pressure
There are many different ways to obtain Nitrous oxide. By heating ammonium nitrate, it will decompose into nitrous oxide and water vapor (NH4NO3 (s) → 2 H2O (g) + N2O (g)). Although this is the most common way to obtain it, there are also other ways, like the Bulgarian's method of heating a solution of sulfamic acid and nitric acid (HNO3 + NH2SO3H → N2O + H2SO4 + H2O). It is also emitted by bacteria in the soil and in oceans.
Nitrous oxide contains two nitrogen atoms and one oxygen atom. The percentage composition by mass is 63.64% nitrogen and 36.35% oxygen. It has a covalent bond.
