Ok, it's technically Avogadro(I think). He's the guy responsible for the pain of calculating moles that I went through in Organic Chem. To this day, I
still can't "get" the concept of moles.

it's just a value....I don't see how people can "not get it"...that's like not understanding 25 or 59. It's just a constant value
that has a lot of practical value in chemistry

I'm not sure if the poster really didn't "get" the concept of a number. My guess is that they really wanted a chance to use a pun that shows
that chemists are really vegetables.

It doesn't matter if AKK didn't get it or not (I seriously doubt he made it to ochem without understanding moles). But soooo many other people have
struggled with it and it really isn't a special concept. It's just plugging in a constant value when necessary.

Friday's comic made me orgasm. Ahhhh...
Wish I had taken O chem. Stupid beginning chem classes were about as much fun as root canals... >_> |

Okay, I'll explain Avogadro's number then.
It's actually 6.02 X 10^23, and it makes much more sense if you measure in metric. one Mol (no e) is a huge number, though makes chemical measurement easy one Mol of water is 18 Millilitres, the atomic weght of water is 18 = hydrogen mass=1 oxygen mass=16, 2 hydrogen, one oxygen. water has an equivilant mass in grams to millilitres. so one Mol of a chemical is an equal weight in grams to that chemicals atomic mass. get it? (hard to believe I failed chem) |

Actually, you kind of confused me again. The best I could grasp was that when you have 6.02*10^23 individual molecules of some combined atoms(which is what a
molecule is), their combined mass in grams is the same value as their atomic weight/mass. Eg, A Mol of Hydrogen is always 1 gram, a Mol of Helium is 4(2? Been
a while), and so on down the Periodic Table. Was still a pain in the ass for me.
I wound up with Organic Chemistry as part of the Biotechnology course that I dropped out of over 10 years ago. Part of the reason being that was a period in my life when I was addicted to video games, and the graduate's guild had no real restrictions on active students spending several hours in there. The reason I qualified for that course was getting a B(60+) in combined Sciences(Physics and Chemistry), of which I skipped the majority of the questions involving Mols and the aforementioned fruity scientist. And any Bio I had was self-taught.
