Question

Residence times at steady state

The mass of ammonia (NH3), nitrous oxide (N2O), and methane (CH4) represent around 1x10^-8%, 3x10^5%, and 7x10^-5% of the Earth’s atmosphere, respectively. (Total mass of the Earth’s atmosphere is 5x10^18 kg.) Calculate the residence times for each of these compounds if their global losses are 5x10^10, 1x10^10, and 4x10^11 kg per year, respectively
