What is the total mass of the Earth’s atmosphere? (The radius of the Earth is

Question

6.37x106m, and atmospheric pressure at the surface is 1.013x105N/m2.)

Answer 1

To calculate the total mass of the Earth's atmosphere, we need to use the formula:

mass = pressure * area / gravity

First, we need to calculate the area of the Earth's surface:

area = 4 * π * radius^2
area = 4 * π * (6.37x10^6)^2
area = 5.12x10^14 m^2

Now, we can plug in the values:

mass = 1.013x10^5 N/m^2 * 5.12x10^14 m^2 / 9.81 m/s^2
mass = 5.26x10^19 kg

Therefore, the total mass of the Earth's atmosphere is approximately 5.26x10^19 kg.
