6.02 x 10^23.
A big number it is. 602,000,000,000,000,000,000,000.
Was thought up by a guy named Amadeo Avogadro. This ug-- I mean, lovely old guy.
It's a big unit of measure that's used to tell how many atoms are in a certain amount of whatever. If you had 12.01 grams of Carbon, you would have 6.02 x 10^23 atoms of Carbon, or a mole of carbon atoms. (By the way, this is an example of molar mass, which can be found on the periodic table).
A mole is biiiig. A mole of papers stacked up could travel to the Moon and back... 80 billion times.
Did I mention it was really big?
And then in class on Thursday, there were tons of hole punches on the floor (although I don't think there were a mole of them!) And we had to calculate the mass in grams of .047 of a mole of atoms in them, and our table won! Theresa, Krystina, and Marcia are hella awesome. :3
Also, Mr. Olson made a video that talks about moles!
