This paper provides a brief history of the molar mass of dry air, Mda, followed by the composition of Earth's atmosphere for the year 2008 and the calculation of Mda. A single equation is given to calculate Mda based on the actual abundance of CO2 in the atmosphere, which is currently ...
molar massof dilution air [g/mol] skiedimo oro molinėmasė, g/mol; EurLex-2 I thought "molecular weight" sounded much less nerdy than "molar mass." Aš pamaniau kad molekulinė masė skamba ne taip moksliukiškai kaipmolinė masė. ...
