Does nitrogen and oxygen weigh the same?
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?
Depends on the temperature and pressure of these gases. In the Earth's atmosphere , oxygen occupies approximately 20% of the volume, and nitrogen occupies approxiamtely 79% by volume. The remaining 1% is occupies by water vapour, carbon dioxide, noble(inert) gases, sulphur dioxide, methane, an trace amounts of other gases.
Why is the percentage of nitrogen the same as when you inhale air and exhale air?
The percentage of nitrogen in the air remains constant when you inhale and exhale because the body does not use nitrogen during respiration. While we inhale oxygen and exhale carbon dioxide, the nitrogen in the air is not chemically altered or metabolized by the body's processes.
What is the ratio for oxgyen with same mass of nitrogen?
Atomic mass ratio for O : N is 15.9994  : 14.0067 .So it takes 14.0067/15.9994 moles of Oxygen to have the same mass as one mole of nitrogen. This is valuated at 0.8754516 to 1.00000
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.

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
Why is the percentage of nitrogen the same as when you inhale air and exhale air?
The percentage of nitrogen in the air remains constant when you inhale and exhale because the body does not use nitrogen during respiration. While we inhale oxygen and exhale carbon dioxide, the nitrogen in the air is not chemically altered or metabolized by the body's processes.
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.
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 if the mass and volume weigh same will they take up the same amount?
That doesn't make sense; a volume by itself doesn't weigh anything, unless you put something inside that volume.
Is oxygen and nitrogen has same numbers of protons?
Oxygen has 8 protons and Nitrogen has 7 protons the atomic number of an element which tell you how many protons an atom has is the lower one seen on each element on the periodic table.
What is the ratio for oxgyen with same mass of nitrogen?
Atomic mass ratio for O : N is 15.9994  : 14.0067 .So it takes 14.0067/15.9994 moles of Oxygen to have the same mass as one mole of nitrogen. This is valuated at 0.8754516 to 1.00000
Can nitrogen rust things?
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.
Weight of a given volume of pure vapor or gas compared to the weight of an equal volume of dry air at the same temperature and volume?
PV = nRTAt a given temperature (T), pressure (P), and volume (V), the number of moles of gas is constant. Thus, whichever gas has a higher molar mass will weigh more. Air is composed of mostly Nitrogen gas (N2), Carbon Dioxide (CO2) and Oxygen gas (O2). The molar masses of these are 28, 44, and 32 respectively.If the pure vapor or gas in question is water vapor (H2O), with molar mass 18, then the air will weigh more.
