• Answer: 46.01g/mole ; Formula of the N & O compound is NO2 ( molar mass of N = 14+ molar mass of O2 (32) = 46 g/mole)

What is the average atomic mass of nitrogen?

The atomic mass of nitrogen is 14.00674 atomic mass units. Nitrogen is a gas that has the atomic number 7 and the chemical symbol N. There are 7 neutrons, 7 protons and 7 electrons in a nitrogen atom. Nitrogen also has stable isotopes, such as N-14 and N-15. Daniel Rutherford discovered this non-metal element in 1772.

What is the molar mass of nitrogen?

The molar mass of nitrogen is 14 gram. Which means every mole of nitrogen has 14 grams of nitrogen in it. Each mole of nitrogen has 6.022 times 10^23 nitrogen atoms in it. This is from Avogadro's number. Now you have to divide the molar mass by Avogadro's number to get the mass in gram for each atom of nitrogen.

In other words, Nature has provided a method to produce nitrogen for plants to grow. Animals eat the plant material where the nitrogen has been incorporated into their system, primarily as protein. The cycle is completed when other bacteria convert the waste nitrogen compounds back to nitrogen gas.

What is the most common use of nitrogen?

The largest use of nitrogen is for the production of ammonia (NH 3 ). Large amounts of nitrogen are combined with hydrogen to produce ammonia in a method known as the Haber process. Large amounts of ammonia are then used to create fertilizers, explosives and, through a process known as the Ostwald process, nitric acid (HNO 3 ).

Is nitrogen a gas?

What is nitrogen in plants?

Nitrogen (N) is an essential element of life and a part of all plant and animal proteins. Nitrogen can be produced in several ways. Some plants, such as soybeans and other legumes, recover nitrogen directly from the atmosphere or from the soil in a process know as "fixation," whereby the plant converts nitrogen into carbohydrates, essential amino acids, and proteins. Nitrogen is commercially recovered from the air as ammonia, which is produced by combining nitrogen in the atmosphere with hydrogen from natural gas. Ammonia is converted to other nitrogen compounds, the most important of which are urea (NH2CONH2), nitric acid (HNO3), ammonium nitrate (NH4NO3), and ammonium sulfate [ (NH4)2SO4]. With the exception of nitric acid, these compounds are widely used as fertilizer.

Where is nitrogen found?

How to extract nitrogen from blood?

The method used a newly developed apparatus for extracting nitrogen or other inert gases from blood by flushing the specimen with another gas. The apparatus consisted of a gas tight syringe modified to incorporate a stainless steel tube with a fine bore lumen which traverses the plunger, creating a gas inlet. To investigate the utility of the new methodology, the apparatus was used in conjunction with a mass spectrometer to measure the blood nitrogen content of healthy normobaric, nonsmoking, adult volunteers. Eleven subjects were studied in the first tests and then blood was obtained from seven of the subjects for repeat analysis several weeks after the first measurements. The mean blood nitrogen was found to be 11.7 microliter/milliliter, in close agreement with values cited in the literature. The variation within subjects for repeat samples was significantly less, p-value less than 0.003, than the variation between different subjects. This suggests there may be true differences in nitrogen content between different individuals. The authors conclude that the new apparatus and methods have a potentially valuable role in future decompression research.

How is nitrogen produced?

Most nitrogen is produced in large tonnage cryogenic distillation plants with oxygen and argon as coproducts. The nitrogen and oxygen are either utilized directly in gaseous form at adjacent industrial facilities with distribution by pipeline, or some or all is liquified to enable distribution and storage in vacuum-insulated vessels. The delivered liquid nitrogen is then used directly or vaporized as needed or is vaporized and stored under pressure in cylinders.

How is nitrogen gas produced?

Nitrogen gas is an industrial gas produced by the fractional distillation of liquid air, or by mechanical means using gaseous air (pressurised reverse osmosis membrane or pressure swing adsorption ). Nitrogen gas generators using membranes or pressure swing adsorption (PSA) are typically more cost and energy efficient than bulk delivered nitrogen. Commercial nitrogen is often a byproduct of air-processing for industrial concentration of oxygen for steelmaking and other purposes. When supplied compressed in cylinders it is often called OFN (oxygen-free nitrogen). Commercial-grade nitrogen already contains at most 20 ppm oxygen, and specially purified grades containing at most 2 ppm oxygen and 10 ppm argon are also available.
