The molar mass of N2O, or nitrous oxide, is 44 grams/mole. Nitrous oxide is a gaseous compound that is often referred to as laughing gas in the medical and dental communities.
Nitrous oxide is a non-flammable, sweet smelling gas when it is at room temperature. At elevated temperatures, nitrous oxide becomes a powerful oxidizer. The gas is often used in dental and surgical procedures as an anesthetic and a pain reliever. When inhaled in large concentrations, nitrous oxide causes patients to feel a sense of euphoria. The chemical compound is also used in the motor racing and rocket industries to increase the power output of engines.
