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.
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.
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.

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
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.

Breathing in pure nitrogen can be extremely dangerous as nitrogen does not support human respiration. When you inhale pure nitrogen, it displaces oxygen in your lungs, leading to a lack of oxygen in the bloodstream, which can result in rapid suffocation and death. It is important to always ensure proper ventilation and air quality to prevent accidental inhalation of pure nitrogen.
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

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.
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.
Carbon dioxide Argon Oxygen Helium Nitrogen
Yes, all samples of pure water have the same mass because the mass of water is determined by its chemical composition, which consists of two hydrogen atoms and one oxygen atom. This means that regardless of the volume or container, the mass of pure water remains constant.
No.
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.
