How many atoms is the earth made of?

Question

The are an unimaginable amount of protons and electrons that compose the earth. How many atoms make up the world? I mean every grain of sand, every drop of water,every organism. EVERYTHING!

If you have the answer, or are even capable of showing that answer, then what would be the estimate for the atoms that make up everything in the known universe? (Assuming that the number is not infinite.)

Answer 1

The quick answer is: more than you can count! But we can get an estimate of the number of atoms in the earth by first knowing what its mass is. The mass of an object is a measure of how much material the object has. The mass of the earth is 5.98*1027 grams. That's the scientific way to write a large number that has a lot of zeros. We can write the mass of the earth with all the zeros like this:

5,980,000,000,000,000,000,000,000,000 grams

Below is a table that shows the breakdown of the fractional amount of the earth for the most abundant types of atoms (also called the element). Some of these values are estimates since we really don't know exactly what the center of the earth is made of but scientists have pretty good theories about it. In the table is also a list of how many grams a mole of an element weighs. The bottom line is that there are about 1.33*1050 atoms in the world. If you want to write it with all the zeros it would be:

133,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000

Answer 3

Anything Isaac Newton didn't understand or give an explanation for, he simply used God as a handy excuse. So there's your answer And when the physicists discover the driving force behind an atom's perpetual motion and energy, then we will simply find something even more obscure to use as a rationale for the existence of God.

Answer 4

The mean density of the luminous universe is estimated at 10^-27kg m^-3, which is on the order of the so called critical density for a flat universe. If you use Hubble's constant as an indication for the universe's radius you'll be able to weigh it.
However, it appears that most of the universe is actually dark (non nonluminous).
This does not allow us to employ standard physics for the estimate you've asked for as we know nothing about the makeup of this dark matter.

Answer 5

That question can't be answered. As the only answer to your question would be infinite. There's no way in knowing the how many atoms the earth is made of.

Answer 6

Well, the number of elementary particles in the entire known universe is "only" 10^80. I've never seen (or can't recall) an estimate for the number of elemntary particles which make up the Earth.

Answer 7

The answer is not infinity. There are 1 / 0 atoms on earth.

Answer 8

hmmmmmmmmmmmmmmmmmmmmmmm

about 60,230,000,000,000,000,000,000
atoms per handful of stuff mostly

Avogadro figured it out

so its grams per mole of whatever

look up the mass of the Earth, then say its sand SiO6 I think just for simplicity

then multiply

there are like 1,000,000,000,000,000,000,000 stars I heard

they are made of Hydrogen mostly I think

so get the average mass of a star

Answer 9

So 2 atoms go into a bar and one says to the other, "I am missing an electron" The other atom says "Are You sure", and the atom replies yes I'm positive........

Answer 10

There are a billion trillion trillion billion atoms that form a 1/2 inch piece of hair...Compare that to the Earth.
