The density of dry air containing N2 varies depending on temperature and pressure. At standard temperature and pressure (STP), which is 0°C (273.15 K) and 1 atm (101.325 kPa), the density of dry air containing N2 is approximately 1.29 g/L. However, at higher temperatures and pressures, the density will increase.

It is important to note that the percentage of N2 in the air is approximately 78%, while oxygen (O2) makes up 21%. Other gases such as argon (Ar), carbon dioxide (CO2), neon (Ne), helium (He), and methane (CH4) make up the remaining 1%.
