Happy Mole Day! In chemistry terms (*not* biology), do you know what a mole is?
It's like a double secret undercover agent! ;-)
Just in case you wanted to learn through music...
6.022 x 10^23 atoms
Started learning about it in chemistry this Monday! BLEH!
I'm not so good with math and such
Until today, I never realized how many bad puns can be created with the word "mole."
Taking ap chem in high school right now
Two days ago I got a .006% error on a lab involving Mg an HCl
.006% in a high school lab
5% is great, 1% is essentially perfect
Lab partner and I celebrated
Avogadro's number is an amount, like a dozen, except a whole lot bigger. It's roughly how many hydrogen atoms you need to amount to one gram: 6.022 x 10^23. To put this into perspective, if you evenly distributed a mole of pennies among all the . . .
. . . people on earth, EVERYONE would receive about $837,805,012,082.92.
I like this plan. Can we do that? Only since that would screw with the world economy, let's give it all to me.
Well, the sheer number of pennies would take up the equivalent of about 1/3 of the Pacific Ocean: 216,792,000 km cubed of pennies (the Pacific Ocean has a volume of about 660,000,000 km cubed).
My finances can be responsible for the rising sea level! Go me!
Yer smart, we get it.
Nerdy girls are soo Hott
I thought Emma was cute, until I found out what a nerd she is. Now I she makes the sun look tepid.
aw, thanks (and llol)
It takes a big bowl to hold a mole of Skittles. A really big bowl.
Surely we can do better than skittles, though...
i hate moles
6.02 x 10^23 molecules. That's the one thing that I remember from chemistry. Also, I've never understood why mole day is 10/23 and not 6/2.
because a lot of schools get out in May ;)
Atoms, not molecules.
Nvm, it can be either.
As a mole represents a large number, clearly the holiday should last from 6/02 until 10/23, every single one a day off from school/work!
Not just molecules
I never took chem...
I know! I went for physics, instead. I don't know why I felt I had to choose.
my major was biochem, but physics is my true love, so I get it. :)
Vaguely. I remember studying it in high school.
In my circle of friends , they call me the "Mole Man" so yes I do!
One mole of a substance equals that substances atomic mass in grams.
6.023x10 to the 23rd molecules. Avagradros number.
It must be 6.022 but anyway I think I remembered pretty well from the 70's.
And more trivia that I remember. In an equation multiply the moles by the gram molecular weight to get the grams of the substance.
A mole is a foreign spy, probably Kenyan, that has infiltrated the US government.
ugh, the word 'Kenya' is disallowed in my polls :p
I remember this. I feel the need to email all my past teachers to let them know haha
Brains and beauty!
Watch out for these two, double threat.
I remember learning about it in tenth grade, but I don't remember exactly what it means. Something having to do with molecules.
My prof opened class with that today haha
A brown spot.
I haven't a clue.
If I hadn't read these comments, I'd never have a clue. I'm pretty damn science illiterate.
aw. I've taught almost every HS science class now, so if there's ever anything you want to know... :)
That's impressive. Haha, I'll try and get a base of understanding with science and if I have a difficult question I'll ask you. Otherwise we'd be here for a long ass time :P
Thank you though, I'll definitely take you up on that sometime.
Great question and pic btw and oso got it correct so I'll quote him "A certain amount of an element. The atomic mass = mass of one mole. Number of atoms in a mole is avogadros number."
A certain amount of an element. The atomic mass = mass of one mole. Number of atoms in a mole is avogadros number.
And avagadros number is how many you put in to make guacamole right.
mmm. I had chem class parties that always included guacaMOLE. and MOLEten chocolate lava cake.
One of our favorite restaurants here is Avogadro's Number. I really don't know why.
Moley, moley, moley!
It is 6.022x10^23 (the number of molecules) this is one mole.
I have chem now and hate it.
Okay I'll love it just for you.
6.022 x 10^23
I know it's a chemical mass, but I haven't done much chemistry lately...
My high school chemistry teacher made a shirt for this day, and she threw a party celebrating the origins...
it's 6.02 x 10^23 particles, in case you're wondering. :)
technically any unit but its only practical with atoms and particles..
I have many good memories of meeting chem students at IHOPs/coffee shops at 6:02 am to celebrate Mole Day. :)
That makes no sense to me.
it's kind of like a dozen is 12 of something, Kay
I am going to blame Mr. Dewey for my lack of knowledge of chemistry! :)
Goalie, you are correct
Chemistry was my worst subject! :(
