We know that the major constituents of the earth's atmosphere are carbon dioxide molecular oxygen (02) molecular nitrogen (n) argon 0.03% 20.95% 78.09% 0.93% the following data are available: mass (kg/kg-mole) 12.01 16.00 14.01 39.95 element ar assume earth's atmosphere is a perfect gas (good assumption). the universal gas constant is r 8,314 j/(kg-mole k). in addition, the standard atmospheric pressure on the earth's surface is 1,013.25 millibars and the standard temperature is 288.16 k. note that a pressure unit is the bar (1 bar 1,000 millibars (mbar)) and one mbar 100 pascals (pa); 1 pa 1 n/m2 what is the specific gas constant, r, for the earth's atmosphere? (you must specify units for r) what is the atmospheric density at the earth's surface?
