What is the mass of nitrogen in grams?
One mole of atoms of an element is equal to the atomic mass of that element expressed in grams. Nitrogen-14 so one mole of nitrogen weighs 14 g
What is nitrogen rule?
If a compound contains an even number of nitrogen atoms (or no nitrogen atoms), its molecular ion will appear at an even mass number. If, however, a compound contains an odd number of nitrogen atoms, then its molecular ion will appear at an odd mass value. This rule is very useful for determining the nitrogen content of an unknown compound.
What mass of hydrogen contains the same number of atoms as 8.65 g of nitrogen?
0,617 g
How many grams of Nitrogen in 76.0 moles of Na2 Cl?
There are two nitrogen atoms in one formula unit of Na2Cl. The molar mass of nitrogen is approximately 14.01 g/mol. Therefore, the total mass of nitrogen in 76.0 moles of Na2Cl is 76.0 moles x (2 nitrogen atoms / 1 formula unit) x (14.01 g/mol) = 2121.52 g.
How many grams of N combine with 7.05x1022 O atoms in N2O5?
The formula N2O5 shows that there are 2/5 as many nitrogen atoms as oxygen atoms in the compound. Therefore, the number of nitrogen atoms required is (2/5)(7.05 X 1022) or 2.82 X 1022 atoms. The gram atomic mass of nitrogen is 14.0067 and, by definition, consists of Avogadro's Number of atoms. Therefore, the mass of nitrogen required to react with the specified amount of oxygen to produce the specified compound is 14.0067 [(2.82 X 1022)/(6.022 X 1023] or 0.656 grams of nitrogen, to the justified number of significant digits.

Why is carbon dioxide heavier than nitrogen?
The density of a gas is proportional to its molecular mass. Nitrogen (N2) contains 2 nitrogen atoms each with a mass of about 14 AMU (atomic mass units) for a total molecular mass of about 44. Carbon dioxide (CO2) contains 2 atoms of oxygen, each with a mass of about 16 AMU and 1 carbon atom with a mass of about 12 AMU for a total mass of 44.
What is the molar mass of a substance that is 23.4 percent N by mass and one molecule contains 5 nitrogen atoms?
The gram atom mass of 5 nitrogen atoms is 5 times the gram atom mass for a single nitrogen atoms, which can be found, in a periodic table or other reference, to be 14.007. Therefore the gram atom mass of 5 N atoms is 5 X 14.007 = 70.035. 23.4 % = 0.234. From the problem statement, the unknown molar mass M of the substance obeys the relationship 0.234 M = 70.035, or M = 299, to the justified number of significant digits.

There are two nitrogen atoms in one formula unit of Na2Cl. The molar mass of nitrogen is approximately 14.01 g/mol. Therefore, the total mass of nitrogen in 76.0 moles of Na2Cl is 76.0 moles x (2 nitrogen atoms / 1 formula unit) x (14.01 g/mol) = 2121.52 g.
What determins the mass number of nitrogen?
The mass number of a nitrogen atom is determined by the mass of the nucleus. As it is the relative mass, it is equal to the combined number of protons and neutrons in the nucleus of the atom. For example, the most common isotope of nitrogen contains seven protons and seven neutrons, giving it a mass number of 14. Some atoms of nitrogen have an extra neutron, which gives a mass number of 15.

What are the nitrogen atoms?
Nitrogen atoms, of course. Naturally occurring nitrogen has two isotopes: nitrogen-14 and nitrogen-15.
What is the mass of 3.01.1021 atoms of nitrogen?
(3.66) There's 2 N and there are 14.00674 atoms so multiple 14.00674 by 2 and you get 28.0138. (3.66)(28.0138/1) = 102.53
