Nitrogen | N (Element)
Nitrogen was discovered by the Scottish physician Daniel Rutherford in 1772. It is the fifth most abundant element in the universe and makes up about 78% of the earth's atmosphere, which contains an estimated 4,000 trillion tons of the gas. Nitrogen is obtained from liquefied air through a process known as fractional distillation.

Dalton's law of partial pressure (article) | Khan Academy
Dalton's law of partial pressures. Dalton's law of partial pressures states that the total pressure of a mixture of gases is the sum of the partial pressures of its components: P Total = P gas 1 + P gas 2 + P gas 3 …. where the partial pressure of each gas is the pressure that the gas would exert if it was the only gas in the container.
Gas Density Calculator
How our gas density calculator works. Our gas density calculator employs this formula: rho = MP/RT ρ = MP /RT to find the density of gas. It takes in the pressure, temperature, and molar mass of gas and calculates the density. Because R R is a constant, we do not require you to enter this value. When you enter these values, the molar mass …
