Nitrous oxide transfer of nitrous oxide from bulk cylinders to smaller, more transportable E-type, 1590 liter-capacity tanks, is legal when the intended use of the gas is for medical anaesthesia. Nitrous oxide Nitrous oxide, commonly known as laughing gas or nitrous, is a chemical compound, an oxide of nitrogen with the formula . At room temperature, it is a colourless non-flammable gas, with a slight metallic scent and taste. At elevated temperatures, nitrous oxide is a powerful oxidizer similar to molecular oxygen. It is soluble in water. Nitrous oxide has significant medical uses, especially in surgery and dentistry, for its anaesthetic and
Gas collecting tube the fluid to be investigated. Measure the overall mass formula_2 to calculate the mass of the fluid inside the tube formula_27 yielding the desired mass density formula_12. If the gas is a pure gaseous chemical substance (and not a mixture), with the mass density formula_12, then using the ideal gas law permits to calculate the molar mass formula_30 of the gaseous chemical substance: formula_31 (formula_32 represents the universal gas constant, formula_33 the absolute temperature at which the measurements took place) Gas collecting tube The characterization gas collecting tube describes an oblong gas-tight container with one valve at either end.
