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.

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.
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.
Is air and oxygen are the same gas?
air has oxygen in it but also other gases, e.g. helium nitrogen.
What mass of oxygen contain same number of molecule as 42g of nitrogen?
Both nitrogen and oxygen exist at standard temperature and pressure as diatomic molecules. Therefore, the relative masses of equal numbers of molecules of the substance will the same as the ratios of their atomic masses, which are 15.9994 for oxygen and 14.0067 for nitrogen. The mass of oxygen that contains the same number of molecules as 42 g of nitrogen is 42(15.9994/14.0067) or 48 g, to the justified number of significant digits.
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
Is nitrogen the same thing as oxygen?
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
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
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.
What gases make up the thermosphere?
Oxygen-20%Nitrogen-80%Helium-1%

What are the two main gases?
Hydrogen and Nitrogen. Or oxygen and carbon dioxide, or carbon monoxide.
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.
Is air and oxygen are the same gas?
air has oxygen in it but also other gases, e.g. helium nitrogen.
