What is the total mass of the Earth's atmosphere? The radius of the Earth is 6.4 *106 m, and 1 ATM = 1.01 * 105 N/m². A)5.3 *1016 kg B)1.1 * 1018 kg C)5.3 *1018 kg D)1.1 * 1020 kg E)5.3 * 109 kg

The mass of the Earth's atmosphere can be calculated by multiplying the atmospheric pressure at sea level (1 atm = 1.01 x 10^5 N/m^2) by the surface area of the Earth (4πr^2, where r is the radius of the Earth). Using the given values, we get:

mass = pressure x area
mass = (1.01 x 10^5 N/m^2) x (4π(6.4 x 10^6 m)^2)
mass = 5.32 x 10^18 kg

Therefore, the total mass of the Earth's atmosphere is 5.3 x 10^18 kg, which is option C.
