How to calculate the molar mass of nitrogen gas?
- Given: d= 2.054g/L ; R = 0.08206 L*atm/mole*K; P= 1atm T =273K
- Required: molar mass= __
- Equation: molar mass = d*R*T/P
- Solution: molar mass = (2.054g/L) (.08026L*atm/mole*K) (273K)/1 atm
- 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 mass of 1 molecule of nitrogen?
Nitrogen is atomic number 7 on the periodic table. A single atom of nitrogen has an atomic mass of 14 (amu or atomic mass units) with 7 protons and 7 neutrons. Nitrogen gas N2 (subscript) has an atomic mass of 28 (2x14).
What is the weight of one mole of nitrogen?
The atomic weight of an element is the number of grams in one mole of that atom. Since nitrogen’s atomic mass is 14.0, there are 14.0 grams of nitrogen in one mole of nitrogen. N2 would be double that, since there are two nitrogen atoms. Therefore, the mass of one mole of nitrogen gas (N2) is 28.0 grams.
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.

How do I calculate molecular mass?
To find the molecular mass, add the atomic masses of all of the atoms in the molecule. Find the atomic mass for each element by using the mass given in the Periodic Table.
How do u calculate atomic mass?
Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
What is meant by 14u?
14u is the transition league that takes players from the "kid" leagues to "young adult" status. It permits a player to play on a diamond tailored to his size and capability rather than being moved to one with twice the playing area in a single year.

Overview
Nitrogen is the chemical element with the symbol N and atomic number 7. Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System. At standard temperature and pressure, two atoms of the element bind to form N2, a colorle…
History
Nitrogen compounds have a very long history, ammonium chloride having been known to Herodotus. They were well known by the Middle Ages. Alchemists knew nitric acid as aqua fortis (strong water), as well as other nitrogen compounds such as ammonium salts and nitrate salts. The mixture of nitric and hydrochloric acids was known as aqua regia (royal water), celebrated for its ability to dissolve
Properties
A nitrogen atom has seven electrons. In the ground state, they are arranged in the electron configuration 1s 2s 2p x2p y2p z. It therefore has five valence electrons in the 2s and 2p orbitals, three of which (the p-electrons) are unpaired. It has one of the highest electronegativities among the elements (3.04 on the Pauling scale), exceeded only by chlorine (3.16), oxygen (3.44), and fluorine (3.98…
Chemistry and compounds
Atomic nitrogen, also known as active nitrogen, is highly reactive, being a triradical with three unpaired electrons. Free nitrogen atoms easily react with most elements to form nitrides, and even when two free nitrogen atoms collide to produce an excited N2 molecule, they may release so much energy on collision with even such stable molecules as carbon dioxide and water to cause …
Occurrence
Nitrogen is the most common pure element in the earth, making up 78.1% of the volume of the atmosphere. Despite this, it is not very abundant in Earth's crust, making up only 19 parts per million of this, on par with niobium, gallium, and lithium. The only important nitrogen minerals are nitre (potassium nitrate, saltpetre) and soda nitre (sodium nitrate, Chilean saltpetre). However, these ha…
Production
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. Whe…
Applications
The applications of nitrogen compounds are naturally extremely widely varied due to the huge size of this class: hence, only applications of pure nitrogen itself will be considered here. Two-thirds (2/3) of nitrogen produced by industry is sold as the gas and the remaining one-third (1/3) as the liquid.
The gas is mostly used as an inert atmosphere whenever the oxygen in the air …
Safety
Although nitrogen is non-toxic, when released into an enclosed space it can displace oxygen, and therefore presents an asphyxiation hazard. This may happen with few warning symptoms, since the human carotid body is a relatively poor and slow low-oxygen (hypoxia) sensing system. An example occurred shortly before the launch of the first Space Shuttle mission on March 19, 1981, when two technicians died from asphyxiation after they walked into a space located in the Spac…
