Question

Assume ideal gas behavior unless otherwise stated

NASA reports that the mean surface pressure of the atmosphere is 1014mbar, the mean temperature is 288K, the mean radius is 6371.000km, and the surface gravity is 9.798ms−2. If the mean molar mass of the atmosphere is 28.97gmol−1 and the composition of the atmosphere includes ?N2=0.78084, ?O2=0.20946, ?Ne=1.818×10−5, ?CH4=1.8032×10−6, then

(a) What is the mass of the atmosphere?

(b) What is the mass of neon in the atmosphere?
