High altitude air composition mole fractions
WebThe mixing ratio CX of a gas X (equivalently called the mole fraction) is defined as the number of moles of X per mole of air. It is given in units of mol/mol (abbreviation for … The three major constituents of Earth's atmosphere are nitrogen, oxygen, and argon. Water vapor accounts for roughly 0.25% of the atmosphere by mass. The concentration of water vapor (a greenhouse gas) varies significantly from around 10 ppm by mole fraction in the coldest portions of the atmosphere to as much as 5% by mole fraction in hot, humid air masses, and concentrations of …
