Scientists Measured the Earth's Weight Using Some of the Tiniest Particles in Existence | Live Science
![SOLVED:The mass of Earth's atmosphere is 5.3 ×10^15 metric tons. The atmospheric abundance of helium is 0.7 ppm when expressed as a fraction by mass instead of by volume, as in Table SOLVED:The mass of Earth's atmosphere is 5.3 ×10^15 metric tons. The atmospheric abundance of helium is 0.7 ppm when expressed as a fraction by mass instead of by volume, as in Table](https://cdn.numerade.com/previews/3d90aa0a-87d5-497d-adcc-057186b483e7.gif)
