Homework Statement
Estimate the total mass of carbon (in billion metric tons, GTC) in the pre-industrial atmosphere with 280 ppm CO2.
Total mass of Earth's atmosphere = 5.4x10^18 kg
Homework Equations
1 GTC = 3.67 GTCO2
1 ppm = 44 AMU/ 26x10^6 AMU
The Attempt at a Solution
44 AMU/29x10^-6 AMU = 1 ppm CO2 = 1.52x10^-6
(1.52x10^-6)(280) = 4.26x10^-4
4.26x10^4 / 3.67 = 1.16x10^-4
