How many atoms is in 1 CM ? Like to many atoms stacked on top of each other to make 1 CM ?

 

It is late, I need to know. I can't sleep. Help.

What ?

Depends on the element.

 

I remember questions like this from Chemistry back in the day, it's really not complex to figure out.

I dont know. Carbon ? Helium ?

Depends on many factors such as element, temperature, pressure.

Atom is mostly empty spaces, there is vast amount of spaces between nuclei and it's orbiting electrons. Pretty sure you can stick a lot of them together if you can overcome repusive charges.

Since no one has helped with this yet, I'll give it a go but be warned, I took chemistry 10 years ago and got a C...

 

As others have said, the answer is not super clear cut, temperature and pressure play into it, as well as the specific element. I'll just be lazy and assume standard temp and pressure. 

 

A quick google search reveals that the density of carbon in it's graphite form is 2.26g/cm^3.

We also know the molar mass of Carbon to be 12.011g/mol. 

 

https://periodictable.com/Elements/006/data.html

 

With this info, we can find how many moles are within 1cm^3, (2.26g) / (12.011g/mole) ~= .188mol

 

A mol is simply a mass of a known number of atoms or molecules, 6.022x10^23.

 

Then we can simply use the known number of mols (.1882) and multiply it by the number of atoms per mol (6.022x10^23) and that will give us the number of atoms in 2.26g, which is the mass of 1cm^3. (.188) * (6.022x10^23) ~= 1.133x10^23 atoms.

 

Again, it's been a really long time since I've done any chemistry stuff so I may very well be wrong, but I figured I'd give it a go.

I think OP is asking for 1CM of atoms in length, not volume.

Well fuck a duck.

 

EDIT: I guess in that case you can simply take the 3rd root of 1.133x10^23, which gives ~48,388,000 carbon atoms in one linear cm.
