∙ 15y agoThe chemical composition of the Earth (by mass) is:
34.6% Iron
29.5% Oxygen
15.2% Silicon
12.7% Magnesium
2.4% Nickel
1.9% Sulfur
http://seds.lpl.Arizona.edu/nineplanets/nineplanets/earth.html
The mass of the Earth is 5.97e24 kg = 5.97e27 g
Therefore the earth contains
2.07e27g Iron
1.76e27g Oxygen
9.1e26g Silicon
7.6e26g Magnesium
1.4e26g Nickel
1.1e26g Sulfur
The molar masses of these elements are:
55.9g Iron
16.0g Oxygen
28.1g Silicon
24.3g Magnesium
58.7g Nickel
32.1g Sulfur
Therefore the number of moles of each of these elements is:
3.7e25 Iron
1.10e26 Oxygen
3.2e25 Silicon
3.1e25 Magnesium
2e24 Nickel
3e24 Sulfur
for a total of 2.15e26 moles. Multiply by Avogadro's number to get number of atoms = 1.3e50 or so.
(what about the earth's atmoshere?)

∙ 12y agothere are 2 billion atoms in a cm. and there are about 24901.55 miles around earth( if your question is how many atoms AROUND EARTH listen up) and there
is 185318.4 cm. in one mile and that times 24901.55 = 4614715403.52 and that
times 2000000000 (2 billion) =4614715403520000000 and that is how many atoms around earth P.S. if you have any complaints a 2nd grade boy wrote this( it's true!

If a mole of atoms were spread uniformly over the surface of the Earth how many atoms would there be per square meter?
A mole of any substance contains 6.02x1023 atoms. The surface of the earth is about 510x106 km2. This surface area is the same as 5.10x1014 m2. Therefore each square meter would have (6.02x1023 atoms)/(5.10x1014 m2) atoms/m2. This reduces to 1.18x109 atoms/m2
Does a penny have more atoms than earth does people?
Yes, most definitely, a penny has many more atoms than the Earth does people.A pre-1982 penny contains about 28,000,000,000,000,000,000,000 copper atoms. Or, 2.8 x 1022atoms.There are about 6 billion people on the planet.
