No, one mole of each, having the same VOLUME (about 22.4 L at STP), differ though in their masses: 32 g/mol for O2 and 28 g/mol for N2
So their densities (mass per volume) also differ in the same way: 1.43 g/L and 1.25 g/L respectively, at STP.

Does pure oxygen and pure nitrogen have the same volume?
No. Oxygen and Nitrogen molecules are not the same size. China has a railroad that rides along at 20,000 feet in Tibet. They pump air into the cars. The cars have filters. Nitrogen gas leaves through the filters and oxygen remains in the railroad cars. By using simple pumps and filters they increase the amount of oxygen in the cars. If oxygen and nitrogen were the same size, it would not work.
Why is the percentage of nitrogen the same as when you inhale air and exhale air?
Percent by volume. Nitrogen is almost insoluble in blood at normal pressures. Oxygen is replaced by carbon dioxide so % nitrogen stays the same.
Does nitrogen and oxygen weigh the same?

Is nitrogen the same thing as oxygen?
no
Can nitrogen rust?
No: Rusting occurs by the combination of ferrous metals with oxygen from air or water, and nitrogen can not form the same compounds as oxygen does.
Why are water molecules lighter than oxygen and nitrogen?
Your question is not worded very well, but this answer is directed at what I think you are trying to ask. Water (chemical structure: H2O) has 2 Hydrogen atoms and 1 oxygen atom. If you add the atomic masses of each of these, you get (1.01+1.01+16.00=) 18.02 atomic mass units (amu). Oxygen gas (O2) has 2 oxygen atoms combined and weighs 32.00 amu. Nitrogen gas (N2) has 2 Nitrogen atoms and weighs (14.01+14.01=) 28.02 amu. The reason why water seems to weigh more than these is because it is a liquid and is more dense. You can fit many more molecules of water into a space than you can of oxygen or nitrogen at normal room temperature and pressure. Because of this, the same volume of water will weigh more than a volume of air (Oxygen or Nitrogen)- it has many more molecules in the same volume.

Equal volumes of nitrogen and oxygen at the same temperature and pressure would?
If equal volumes of nitrogen and oxygen are at the same temperature and pressure, then both (the nitrogen and oxygen) will contain the same number of particles

no
In a nitrogen plant you get nitrogen by separating oxygen. Can you also recover oxygen simultaneously with nitrogen?
yes because if it is gathered, we will sstill have the same atmosphere
The gases in a mixture have the following partial pressures at the same volume and temperature 1013000 Pa nitrogen 700 mm argon 1.20 ATM of helium 790 torr oxygen and 0.50 ATM of carbon dioxide?
Carbon dioxide Argon Oxygen Helium Nitrogen
What do animals use nitrogen for?
The same reason humans do. People breath oxygen and nitrogen.
What gas diffuses at the same rate as nitrogen?
Oxygen
Which gas is heavier oxygen or nitrogen?
Since both form diatomic elements, we simply have to compare molecular masses. O2 has a mass 32.0 g/mol, while N2 is 28.0 g/mol. This means that, since gases (according to the ideal gas law) all contain 22.4 mol/L, then the same volume of oxygen would be heavier than the same volume of nitrogen.
Can nitrogen rust?
No: Rusting occurs by the combination of ferrous metals with oxygen from air or water, and nitrogen can not form the same compounds as oxygen does.
