Calculating the mass of the earth's atmosphere

  1. Jul 31, 2012 #1
    1. The problem statement, all variables and given/known data
    Given that the radius of the earth is 6.4 x 10^6 m, the total mass of the earth's atmosphere is approximately________kg?

    Choices:
    a) 5 E16
    b) 1 E18
    c)5 E18
    d)1 E20
    e) 5 E9

    2. Relevant equations

    What is the depth of the earth's atmosphere? What is the density?

    3. The attempt at a solution

    You don't need to know the depth of the Earth's atmosphere to answer this question, or it's density. What is the pressure at sea level? Pressure is what divided by what?
