Volume of a sphere?? Does it have to do with density

I looked it up the conversion. I thought it might be in the problem but I can'tseem to find it working backwards

14.7psi x 702771g/m2 x 1kg/1000g= 10331kg/m2 of air above surface A=4pieR2=1.97x10'8mi2 x (1km/.6214)=5.11x10'14m2 surface area 5.29x10'18 mass of atmosphere!?

ok thanks. i'll try to look up the difference b/c we have not covered this distinction in class

sorry typed it wrong. i reposted my work. i don't know where else to go

Homework Statement above each square ince of the Earth's surface is 14.7 pounds of air. the density of air at sea level is 1.27g/l. the Earth is 7930 miles in diameter and has a mass of 5.98x10^24kg. use this data to determine the mass in kg of the Earth's atmosphere determine the...
