Question
The atmosphere contains about $5.2 \times 10^{15} \mathrm{t}$ of air. What mass in metric tons of carbon dioxide is in the atmosphere if the concentration of $\mathrm{CO}_{2}$ is $394 \mathrm{ppm} ?$
Step 1
Since 1 ppm is equivalent to 0.0001%, we multiply the given concentration by 0.0001%: \[394 \, \mathrm{ppm} \times 0.0001\% = 0.0394\%\] Show more…

The concentration of carbon dioxide in the atmosphere has been increasing since the industrial revolution. In 2001, the concentration was 369 ppm (parts per million) and today (in 2019) it is 413 ppm. Assuming that the mass of the atmosphere is 5.2 × 10^18 kg and has an effective molar mass of 29.0 g/mol (~80% N2, 20% O2), how many kg of CO2 have been added to the atmosphere since 2001? Note: 1 ppm = 1 µmol per mole of air.
9. Since the Industrial Revolution, the atmospheric concentration of carbon dioxide has increased from 280 parts per million to 380 parts per million. The mass of Earth’s atmosphere is estimated to be 5.3 × 10¹⁸ kg. What mass of carbon dioxide has been added to Earth’s atmosphere?
The atmospheric concentration of $\mathrm{CO}_{2}$ gas is presently 390 ppm (parts per million, by volume; that is, $390 \mathrm{~L}$ of every $10^{6} \mathrm{~L}$ of the atmosphere are $\left.\mathrm{CO}_{2}\right)$. What is the mole fraction of $\mathrm{CO}_{2}$ in the atmosphere?
